WWF is supporting the research of the Catlin Arctic Survey. This year’s research includes an expedition across the ice, as well as an ice base, both in the far north of Canada. The main purpose of the mission is to gather data on the changing Arctic Ocean currents.

It’s exciting to be here in the Catlin Ice Base at the seasonal change from winter to spring. Warmer temperatures make living on the sea ice much more pleasant, and the plankton world is feeling the coming of spring too. Continue reading

If you want to understand how ocean acidification might impact some marine creatures you need to do two things. First go to the seaside and find a seashell. Then go to a shop and buy a fizzy drink, any brand will do. Put the seashell in the fizzy drink and leave it for a few days. You will see that it is starts to dissolve away.
A similar process is happening in the oceans today. Carbon dioxide in the atmosphere is being absorbed into the ocean. When carbon dioxide dissolves in water it forms carbonic acid. Fizzy drinks are carbonated – they have carbon dioxide bubbled into them and this makes them acidic. Carbon dioxide is taken up into cold waters more rapidly and so the process of ocean acidification affects the coldest seas, such as the Arctic Ocean, the most. Continue reading
In search of the extraordinary: Chukchi Sea polar bear research
Geoff York, the WWF Global Arctic Programme’s resident polar bear expert, is in the field in the Chukchi Sea, Alaska, working with bears for the 14th year in a row. Read his previous posts here and here.

Finally – a banner morning: clear, nearly calm, and should reach +5F by this afternoon. The team was joined by a second small helicopter late last night that will act as a spotter and may also haul extra fuel later in the season when the sea ice become too broken for the fixed wing to land. We meet at 8 AM for our briefing and plan to launch around half past ten. We will also have our fixed wing spotter/fuel plane today, so pilot coordination will be important.
Following the high winds this week, we are expecting that any old tracks will be well drifted, which should help us. However, snow scour (loss of snow) and hard pack will make new tracks harder to find. Good thing we will have a few more eyes on the ice today.
Polar bear tracks on hard-packed snow are difficult to see from the air and even more difficult to follow any distance.

Did you know there are 200 billion more copepods than people on the planet, and even though they are small, their combined mass is over 400 times that of the human population? At their fastest, they travel a hundred times faster than Usain Bolt. Continue reading
Watching and waiting with windy weather: Chukchi Sea polar bear research

It’s a blue sky day this morning, with the looming threat of worsening conditions later this afternoon. From the weather service map, we are in the middle of the only stretch of coast across the entire state of Alaska (more coastline than the rest of the US combined) that is under visual flight rules (VFR). Limited visibility from snow, blowing snow, or fog dominates the weather elsewhere. We find ourselves in the gap between a high pressure system over Chukotka and two deep lows pushing across the Bering Sea. With any luck, we’ll escape the snow – but we will not escape the wind.

The journey north: Chukchi Sea polar bear research
By Geoff York
Fourteen years. It’s difficult to believe that this will be my fourteenth consecutive year conducting polar bear captures in Alaska. From my first fall capture season in 1998, I always assume that each season and year will be my last such opportunity. Why? Because so few people have the opportunity to work out on the frozen seas, and fewer yet with an animal as magnificent as the polar bear. It is both an opportunity and a real honour and one I do not take for granted- every flight, every day, every year.
Thursday, March 31
Today I am flying north from Anchorage to a field camp just north of Kotzebue along the shorelines of the Chukchi Sea. I’ll be joining the US Fish and Wildlife Service Chukchi research team led by Dr Eric Regehr and Dr Karyn Rode. They have been at the field station for two weeks and have captured 29 bears – mostly family groups and young single animals, but all in good condition.
This will be their 4th year of research in the Chukchi Sea, an area where we have significant need for more information on the shared polar bear population with Russia. The data gathered through this project will shed significant light on the current status of these bears and inform future management decisions. It will also expand our understanding of how polar bears in different geographic areas are responding to rapid changes in sea ice. Additional research will be required on the Russian side in coming years to complete this story, and both WWF and the USFWS are working with partners in Russia and Chukotka to fill that knowledge and capacity gap.

The storm that ‘drifted’ over us on Sunday didn’t really show its full strength until later on in the week. Winds increased to about 20 knots, gusting 30 knots at times, with snow being blown across the ground it reminded me of being a kid walking across a beach on a stormy autumn day with sand blowing all around me. It doesn’t take long for the winds to transform the snow, and drifts quickly formed around all our tents. Continue reading
