A`LA CARTE: ICY COLD SCIENCE

Summer is coming. The time of camping and icy cold drinks. I've been working on developing a freeze dried beer that comes in a small pack and rehydrates fully carbonated with all its alcohol intact. Once it goes to market you can say you knew me when. In the meantime, I can help with getting that warm six pack or vodka cooler cold in minutes. Geeky, yes, and yet you'll be so much more popular at summer parties.

Understanding how salt and ice interact will save you from many a warm bevvie this summer. Water freezes at 32 degrees F. (0 degrees C ) When the compound salt is added to water and ice, a new solution with a lower freezing temperature is formed. As the salt and ice molecules mix, the melting ice takes up heat energy from its surroundings and the surrounding water cools down fast.

Why should you care? Well, this little scientific nugget can keep you from ever having to drink warm drinks again. Instead of dropping your warm beverages into a cooler with ice, try adding water and a healthy dose of salt. And, there's no need to worry if some of that salt spills over into your drink. A little salt is good for you. Balances the electrolytes and makes tequila go down easier.

If you are in North America, you will likey be using iodized salt, which is table salt mixed with a minute amount of potassium iodide, sodium iodide, or sodium iodate. Iodized salt is used to bump up the amount of iodine in our systems and protect us from endemic goiter, a thyroid condition that arises from lack of iodine. In Europe, sodium fluoride or potassium fluoride is the more common additive, especially if they do not add fluoride to their drinking water. You may notice this in France. You'll also notice a slight yellowish tinge to the salt. Don't panic. Different culprit than yellow snow. They add a wee bit of Vitamin B9, hence the discoloration.

No matter which salt you choose, bada bing... icy cold bevvies in minutes.

ROMANIA: 35,000 YEAR-OLD HUMAN REMAINS















If Van Helsing were poking around Transylvania these days, chances are he'd be more likely to be looking for the decaying remains of 35,000 year old humans than blood drinking vampires. Romania's dark history extends back way past the days of Vlad.

It seems vampires and ghouls aside, something darker and much more interesting lurks in that eastern belly. I travelled to Transylvania last year and spent some time in Cluj, the newly minted anthro-capital of Romania. I was lucky enough to brush shoulders and prep tools with paleoanthropologists working on a new find that changes what we know about early human activity in Eastern Europe.

The remains of a man, woman and teenage boy -- the first Romanian family if you will... tell the most complete picture of what our ancestors were like some 35,000 years ago, shedding a bit of light on a black box in history. International scientists have been carrying out further analysis to get a clearer picture on the find, said anthropologist Erik Trinkaus, of Washington University in St. Louis.

It is clear that, "this is the most complete collection of modern humans in Europe older than 28,000 years," he told The Associated Press. "We are very excited about it," And they have reason to be. The find is changing perceptions about modern humans. Romanian recreational cavers unearthed the remains of three facial bones last year, and gave them to Romanian scientists. Romanian scientists asked Trinkaus to analyze the fossils, and he traveled to the Romanian city of Cluj this week with Portuguese scientist Joao Zilhao , a fossil specialist.

They also found a jawbone that belonged to a man who could have been around 35. Silhao also found part of a skull and teeth belonging to a teenage male, and female temporal bone.

"This was 25,000 years before agriculture. Certainly they were hunters," said Trinkaus . He said the bones were discovered in the foothills of the Carpathian Mountains . Trinkaus said the humans would have had religious beliefs, used stone tools, and a well-defined social system and lived in a period in during which early modern humans overlapped with late surviving Neanderthals in Europe.

Humans survived because the area was ecologically variable being close the Banat plain and close to the mountains. A team of international scientists from the United States , Norway , Portugal and Britain will return to the cave to continue their field work next year. Look out Van Helsing, there are new kids in town and they look to be very, very interesting.

DINOSAUR DISCOVERY IN TUMBLER RIDGE

Today is the First Annual Peace Region Palaeontology Symposium in Tumbler Ridge, an an important milestone for Tumbler Ridge and the Peace Region. Daniel Helm's find of dinosaur tracks along a river near the town of Tumbler Ridge sparked a new paleo craze in the town. I met with Daniel and Charles Helm back in 2005 at the British Columbia Paleontological Symposium. The photo above is from their original workshop that has now blossomed into a fully operation paleontological centre.

Congrats to the Peace Region Palaeontological Society! I'm sure this symposium marks the first of many great educational events.

GODS & CEPHALOPODS

A great temple to the god Amon was built at Karnak in Upper Egypt around c. 1785. It is from Amon that we get his cephalopod namesake, the ammonites and also the name origin for the compound ammonia or NH3.

Ammonites were a group of hugely successful complex molluscs that looked like the still extant Nautilus, a coiled shellfish that lives off the southern coast of Asia. While the Nautilus lived on, ammonites graced our waters from around 400 million years ago until the end of the Cretaceous, 65 million years ago.

Varying in size from millimeters to meters across, ammonites are prized as both works of art and index fossils, geological time markers, helping us date rock. They have proven especially useful for proving time markers for the strata of the Cretaceous System along the west coast of North America.

The ammonites with their hard exoskeleton, chambers and soft interior, were kissing cousins in the Class Cephalopoda, meaning "head-footed," closely related to modern squid, cuttlefish and octopus. Cephalopods have a complex eye structure and were excellent swimmers. Ammonites used these evolutionary benefits to their advantage, making them one of the most successful marine predators of ancient Cretaceous seas.

PADDLING WIDGEON ESTUARY


Interested in getting out on the water? Head out for a relaxing day paddle or overnight to Widgeon Estuary. The paddling is easy. You can do the trip via kayak or canoe and can stay for the night or do it as a day trip. I like to to camp near the base of the trail to the falls.

There is nothing better than to cruise flat water with rippling reflections of big snowy mountains cascading off your bow. The estuary of Widgeon Creek at the south end of Pitt Lake at Grant Narrows is the perfect place to enjoy this sensation.

If you like quiet peaceful waterways teaming with bird life this is the place to go for the whole estuary is a protected bird sanctuary. After making the 300m crossing of Grant Narrows, expect to see tons of waterfowl and other species from herons to harlequins that make this area their habitat. You might even see a fleeting glimpse of muskrat or beaver if you are lucky.

If Widgeon Creek is high in the spring or early summer you can paddle quite a distance up under lazy overhanging branches draped in moss and lichen. Huge lush ferns and skunk cabbage line the shoreline in the marshy areas and neat little gravel bars are gathered in the bends of the creek. When you are there you will be amazed that you can be so close to the city yet so far away.

A campsite is located near the west end of the estuary if you want to stay longer. This is probably best to do in the shoulder season when it isn't so busy. If the water is high more secluded sites are located up the river.

EIGHTH BC PALEONTOLOGICAL SYMPOSIUM

KWAK'WAKA'WAKW MATRILINE AND PATRILINE

The Kwakwaka’wakw are characterized by a particular iconographic promiscuity, a tendency to mobilize a diverse set of visual, material, or performative signs that index their individual standings. There may be various explanations for this. 

The Kwakwaka’wakw are geographically and culturally at the point on the central coast where the strictly matrilineal groups of the north (e.g., Tlingit, Haida, Tsimshian) give way to more patrilineal and less clan/crest-based patterns of descent in the south (Nuu-Chah-Nulth and Coast Salish), and they have long been known as the grand synthesizers of the region. 

Bilateral reckoning of Kwakwaka’wakw descent entails the claiming of crest images and personal prerogatives from both the matriline and patriline, increasing the number of images an individual might legitimately display. 

They developed and maintained through the assimilationist period the most elaborate system of restricted ceremonial performance of the famous ‘‘secret’’ or ‘‘dance’’ societies described by Franz Boas (1897) and Philip Drucker (1940) which is predicated on rather flexible and negotiated hereditary rights to (often multiple) ritual dramas and the accompanying regalia (see Roth 2002:144). 

The Kwakwaka’wakw have long proved remarkably amenable to participating in their own ethnographic representation, from adapting their visual motifs and performances to intercultural contexts of display, to applying the technologies and institutions of modernity to their own modes of cultural production (Glass 2004, 2006)

INSIGHT: ICE CORE LOOKING GLASS

Evidence from the past provides a window into the Earth's future. A sediment core from 400m below the seabed of the Arctic Ocean showed that Fifty-five million years ago, deep in the Eocene, the North Pole was ice-free and enjoying tropical temperatures. It also tells us that the temperature of the ocean was 20C, instead of the coolish –1.5C we see today… a truth that is hard to imagine with all the press surrounding global warming.

The bottom end of that core helped explain the fossils found at Eocene sites around British Columbia, species commonly seen in more tropical environments today. The warmer temperatures seen at McAbee and around the globe were recorded in the core sample and reveal evidence for a global event known at the Palaeocene-Eocene Thermal Maximum. Back in the Eocene, a gigantic emission of greenhouse gases was released into the atmosphere and the global temperature warmed by about 5C.

While the bookends of the geologic time scale slide back and forth a wee bit, the current experts in the geologic community set the limits to be 33.9 +_ 0.1 to 55.8 +_ 0.2 million years ago. The fossil record tells us that this part of British Columbia and much of the Earth was significantly warmer around that time, so warm in fact that we find temperate and tropical plant fossils in areas that now sport plants that prefer much colder climes, or as is the case in the Arctic, snow and ice.

The Okanagan Highlands is an area centred in the Interior of British Columbia, but the term is used in a slightly misleading fashion to describe an arc of Eocene lakebed sites that extend from Smithers in the north, down to the fossil site of Republic Washington. The grouping includes the fossil sites of Driftwood Canyon, Quilchena, Allenby, Tranquille, McAbee, Princeton and Republic. These fossil sites range in time from Early to Middle Eocene, and the fossil they contain give us a snapshot of what was happening in this part of the world because of the varied plant fossils they contain..

While the area around the Interior of British Columbia was affected. McAbee was not as warm as some of the other Middle Eocene sites, a fact inferred by what we see and what is conspicuously missing.

The plant species suggest that McAbee had a more temperate climate, slightly cooler and wetter than other Eocene sites to the south at Princeton, British Columbia and Republic and Chuckanut, Washington. Missing are the tropical Sabal (palm), seen at Princeton and the impressive Ensete (banana) and Zamiaceae (cycad) found at Republic and Chuckanut, Washington.

While we are the likely culprits of much of the warming of the Arctic today, the sediments of McAbee tell us that natural processes operating in the not too distant past have also resulted in significant temperature fluxuations on a world-wide scale.

"LOOK, LOOK, LOOK" A DAY AT THE ZOO

If you are feeling a bit hemmed in from all the cold weather, bundle up and take a trip to the Vancouver Aquarium, Science World or your local museum.

There is nothing more exciting than witnessing the awe on a child's face as they begin to explore the natural world.

If you've got a thing for fossils, remember to check out the ancient critters as well. The Royal BC Museum, Qualicum Beach Museum an Courtenay Museum all have permanent fossil displays. If you are in Vancouver, head on down to Science World to see their T-Rex. There re also many fossil exhibits planned at the new Beatty Biodiversity Museum openig later this year at UBC.

ALCES ALCES: MOOSE

The moose is the largest member of the deer family. The genus and species of the moose are Alces alces.

Moose are found in northern forests in North America, Europe, and Russia. In Europe and Asia, moose are called elk. Moose are solitary animals who have a deep call and a strong scent.

They have a life span of about 17 years in the wild. If you ever have the pleasure of paddling the Bowron Lake Circuit, there are many great viewing spots which provide excellent photo ops for Moose.

Anatomy: The moose is about 7.5 feet (2.3 m) tall at the shoulder. Only the male moose, bulls, have antlers. The largest recorded antler spread is over 6.5 ft (2 m). The antlers are shed each year and regrow. Moose have hoofed feet, long legs, thick brown fur, a large body, and a droopy nose, and a dewlap (a flap of skin hanging loosely from the chin).

Behavior: The moose is an herbivore (a plant-eater) who spends most of the day eating. Moose prefer willow, birch, and aspen twigs, horsetail, sedges, roots, pond weeds, and grasses. They are excellent swimmers, strong runners and can turn on a dime. I've seen a Moose outrun a grizzly up near Barkerville on the Bowron Lake circuit.

Predators: The grizzly bear and man are the main predators of the moose.

AURORA BOREALIS

TIME FOR LUNCH

Tormented cries from mother as her cub is butchered and eaten...

Does it pull at your heart strings? Mine, too.

A rally of cries about a shark attack generally bring something less warm and fuzzy, something closer to terror and visions of a nasty end for some surfer. No surfer this time.

The 20th Century's most significant marine find became surf and turf himself at a recent feast in a village off the coast of Donsol in the Bicol Region of the Philippines.

More than a rare sighting, this is the 41st specimen ever known. A massive Megamouth, a rare breed of filter-feeding shark, was caught and killed then served up to locals eager to consume the traditional delicacy despite protests from the World Wildlife Federation.

While WWF tried to convey the magnitude of the slaying the world has to wonder if more should have been done. This was more than a rare sighting, this specimen was the 41st ever recorded of Megachasma pelagios.

Panda! Not this time. It was a deliverate ploy to get you to ponder your feelings on slugs vs. bunnies. If it is what enticed you to take a peek, however, perhaps we need to rethink our treatment of the ugly ducklings out there.

We tend to favour cute and cuddly. Dark grey, menacing distant cousins of Jaws don't bring out the maternal instinct quite as readily. Had this been a sighting of a rare panda set to be slaughtered to make soup with his paws, I'm sure Megamouth would have made both CNN and the BBC.

Might isn't right, but something more than sway was needed here.

HURDIA: BIZARRE FIND EXCITES SCIENTISTS

Scientists from Sweden’s Uppsala University have pieced together a bizarre marine predator who trolled the seas some 505-million years ago. Hurdia, had a giant head, protruding shield and claws for capturing prey. Bits and pieces of Hurdia have shown up in museums all over the world. Until now, they’ve been left unidentified or wildly mislabeled. Allison Daley, the lead author on the study, is set to publish in this month’s journal Science.

Just when you thought it was safe to go back in the water…

MAMMALS

Mammals come in all shapes and sizes, and can be found all over the earth and come in all shapes and sizes. There are around 5500 species of mammals in all. You are a mammal, all of your friends are mammals and so is your dog. All mammals are warm-blooded and have either hair or fur on their bodies. The majority of all mammals give birth to live young, but there are a few species of mammals that lay eggs. The Triassic period, 220 million years ago, was the age that the first mammals can be found.

During the Triassic period, about 220 million years ago, the first Mammal species were roaming the Earth. These mammal ancestors were preceded by a group called the 'synapsids'. There were three distinct groups of creatures prior to the Triassic period, of which 'synapsid' is one. The others are 'diapsids' and 'anapsids'. The terminology makes reference to the holes on their skulls where the jaw muscles attach. 'Synapsids' (mammals) have one hole on either side, 'diapsids' (dinosaurs, reptiles, birds) have two holes on either side, and 'anapsids' (turtles) have none.

WORLD THROUGH A LENS

ALPILLES

CLAM STEW: THE FOSSILS OF SOOKE

Sunshine, salt air, the bark of seals and fossils await for those lucky enough to beach comb the sandstones of Sooke on Vancouver Islands' southwestern edge.

Friends had the chance to collect there recently and found a number these lovely marine fossils near the exposure at Muir Creek.

Here you can see a budding paleontologist, holding some of his finds - blocks of late Oligocene, 20-25 million year old, sandstone full of small gastropods, bivalves and barnacle bits of the Sooke Formation.

By the late Oligocene ocean temperatures had cooled to near modern levels and the taxa preserved as fossils bear a strong resemblance to those found living beneath the Strait of Juan de Fuca today. Mammal material, echinoids, coral, chitin and limpets are also found here.

The largely intertidal assemblage of fossil species tell us that the formation was layed down near shore and the thickly strewn layers we see as blocks and in the nearby cliffs suggest that they may have been deposited along a strand line.

TY COLLWYN WATERFRONT RETREAT

If you are looking for a great place to stay, try the Ty Collwyn Waterfront Retreat, a fabulous B&B nestled on Sooke Harbour.

Ty Collwyn Waterfront Retreat offers private, oceanfront, two bedroom cottages within walking distance from the heart of Sooke, on Vancouver Island. We are located just forty minutes west of Victoria; the capital city of British Columbia, Canada.

Each cottage has an ocean view of Sooke Harbour and the Juan de Fuca Strait, private deck and hot tub. Yes, something like heaven!

The grounds include a heated indoor pool, coin-operated laundry facilities, private dock, and waterfront with a fire pit, all surrounded by lush trees and an acre of grass area.

EATEN ALIVE: SHRIMP BEATS GOLIATH

What looked to be a small stroke of genius in the fight against global warming has resulted in huge disaster.

Planktos, a California-based company that sells “carbon credits” to businesses looking to reduce their carbon footprint and contribution to global emissions has been taken down by a swarm of shrimp. They had planned to harness the photosynthetic power of algae to lower greenhouse gases.

Algae come cheap, requiring light and water. They also require iron, which may be the sixth most abundant element in the Universe, but still relatively rare in the ocean. The small bits algae utilize are blown in by the wind and runoff from rivers and streams.

While some scientists and environmental groups object to their plan fearing harmful changes to the ecosystem, Planktos went ahead and dumped a hundred tons of iron dust mixed with seawater into international waters off the coast of the Argentina.

Expecting a plankton bloom and carbon credit riches to follow, their plans were literally eaten alive by a swarm of algae-loving shrimp. They did get their bloom, but it was not the algae they were expecting.

Instead of large diatom algae, they got millions and millions of haptophytes, a tiny algae common in the open ocean and extremely abundant in the fossil record. They are also the fellows responsible for the white foam you sometimes see on the edge of beaches.

Most importantly, however, they are the food of choice for the equally common copepod, a shrimp-like crustacean who complete with krill for forming the largest animal biomass on earth. And perhaps, having the largest appetite.

Sometimes brilliance arises from thinking outside the box. Sometimes not. The copepods ate all the haptophytes and Planktos' dreams. It seems the wee shrimp-like fellows didn’t get the memo. Instead they got an all you can eat coupon to a fine seafood buffet.

MARINE BEAUTIES FROM JURASSIC SEAS

A surprisingly warm sunny morning sparked a return trip to the Cretaceous-Jurassic exposures near Harrison Lake, British Columbia. The lake and hotsprings at Harrison are an easy one to two hour drive from Vancouver. My work leads me a ways past the town exploring logging roads along the lake.

Without goggles you could easily lose an eye working the unyielding siltstones. Much of my collecting was spent wincing as small, bullet-like projectiles went pinging past my face… others making contact but not enough to deter my efforts. No pain no gain.

After a few hours of work I've done pretty well. Looking down at my pack I'd managed to unearth a fine selection of ammonites of the Callovian Mysterious Creek Formation, including the small, fairly well preserved Cadoceras (Paracadoceras) tonniense and smallish Cadoceras (Pseudocadoceras) grewingki. The other bits and pieces were mostly fragments but included one relatively complete specimen of the larger, smooth Cadoceras comma and some perfectly preserved belemnites, cigar-looking numbers from ancient squid. For interest, I've popped in an image of an ammonite from Fernie. I'll post one of the ones from Harrison when I did out my digital.

Interestingly, the ammonites from here are quite similar to the ones found within the lower part of the Chinitna Formation, Alaska and Jurassic Point, Kyuquot, on the west coast of Vancouver Island. I'll have to write up the trip I did with the VIPS to Kyuquot a few years back. We enjoyed fantastic scenery and wild west coast adventures. I'd like it on record that that was not the trip the coast guard had to be called, but it remains memorable from the great company, fantastic fossils and the fact that my car was stolen at some point. Ah, living.

The siltstone here at Harrison has also offered up a small section of vertebra from a poorly preserved marine reptile, a find I'm rather keen to make one day. So, after much hammer swinging, I've enjoyed a splendid day, collected beautiful specimens and feel a wee bit closer to the big find. Returning like a soldier from battle, I carefully package and log my booty, returning home the happier for it.

I'll be heading back to the fossil beds of the Myseterious Creek Formation at Harrison on Monday, May 18, 2009, as part of a fossil field trip for the 2009 BC Paleontological Symposium. If you're about, feel free to pop by and say hello. I drive the big black tank, and yes, it's alarmed!

505-MILLION YEAR OLD MYSTERY SOLVED

Scientists from Sweden’s Uppsala University have pieced together a bizarre marine predator who trolled the seas some 505-million years ago. Hurdia, an extinct species of anomalocaridid, had a giant head, protruding hollow spike-shaped head shield and spiny claws for capturing prey. They look to have made a living swimming in the water column clawing around for prey to scoop into their tube shaped mouths. They lived at the time of trilobites, tuzoia and other soft-bodied marine creatures long extinct.

Bits and pieces of Hurdia have shown up in museums all over the world. Until now, much like their more robust cousin, Anomalocaris, they’ve been left unidentified or wildly mislabeled. Imagine Leggo clicked together sideways, upside down or split in two. Scientific papers have documented the many attempts at getting it right with respect to their body design.

Allison Daley, lead author on the study, is happy to set the record straight and will publish the groups findings in this month’s journal Science.
