Arctic Food Web Melting Along With Thick Sea Ice Wwf A new paper suggests that the arctic's rapidly disappearing older ice plays a larger role in arctic ecology than previously thought. while an increasing percentage of arctic sea ice melts each summer, a portion of the arctic ocean remains covered in ice year round. new research on ice cores sampled from this multi year ice show thriving. A threat to food webs, biodiversity and food security. given expectations that both temperatures and sea ice loss will continue to increase, the lower ph and decreased aragonite saturation state in the summer arctic ocean may cause more severe acidification. this would be bad news for arctic sea life, food webs, ecosystems and indigenous peoples.
Arctic Ecosystem Food Web Since then, we have observed that the ice has decreased from 2.7 metres in thickness to approximately 1.7 metres, on average. at the same time, satellites have also recorded a significant decrease in sea ice extent. putting these changes together tells us that the arctic has lost nearly 50 per cent of its sea ice volume in the past few decades. The report warns summer sea ice will be lost completely in a two degree world — we’re currently on track to hit 3°c — threatening arctic wildlife and communities. melting permafrost will also destroy most infrastructure and release previously trapped methane. ocean: polar glacier and ice sheet melt is now the largest contributor to sea. Thanks to the thickness of multi year pack ice and north america’s last remaining ice shelves, it could become a final refuge for sea ice dependent species like narwhal, polar bear, walrus, seal and beluga as well as the under ice algae that fuels the entire arctic food web. the last ice area is a vital climate adaptation effort. Thanks to the thickness of multi year pack ice and north america’s last remaining ice shelves, this region could become a final refuge for sea ice dependent species like narwhal, polar bear, walrus, seal and beluga, as well as the under ice algae that fuels the entire arctic food web. but sea ice can only continue to play this pivotal role if.

Polar ice caps are melting as global warming causes climate change. we lose arctic sea ice at a rate of almost 13% per decade, and over the past 30 years, the oldest and thickest ice in the arctic has declined by a stunning 95%. if emissions continue to rise unchecked, the arctic could be ice free in the summer by 2040. The walruses climb on to shore because of declining sea ice cover. “typically, walruses spend most of their time at sea hauled out on ice floes as they forage for food on the ocean floor” explains wwf’s nikhil advani, “but as sea ice declines, they’re increasingly hauling out on land instead.”. in september 2014, noaa aerial surveys.
