Spencer Glacier Collapse

Andrew Hooper e Josh Basty, dois canoístas de kayak testemunharam o glaciar 
Spencer colapsou, mesmo bem perto. Um susto enorme!

Ambos tinham as câmaras apontadas para o colapso que fora anunciado. Mas o susto foi grande! Não esperavam tão forte abalo.

Andrew Hooper e Josh Basty trabalham nos canais YouTube de Steering South e Home With the Hoopers.

No vídeo publicado por um dos canoístas ouve-se o gelo a quebrar e, uns minutos mais tarde, vê-se o glaciar a colapsar com violência na água. Nesse momento é projectada uma massa de água na direcção dos dois homens.
Um dos protagonistas da história com final feliz grita "Temos sorte de estar vivos".



Two kayakers just escaped with their lives after a massive glacier collapsed in front of them in Alaska.
A glacier has collapsed and sent a wall of icy water straight at two kayakers who had approached the cliff after hearing cracking noises.

Two kayakers at Spencer Glacier in Alaska are lucky they weren’t any closer to a glacial bridge that collapsed or it could have been catastrophic. As it was, Josh Bastyr and Andrew Hooper were pelted pretty good from the explosive fallout, as captured in Bastyr’s Steering South video (the real action begins at the 40-second mark).
The incident occurred last Saturday 17 August during an overnight camping and kayak trip to Spencer Glacier. 


The kayakers filmed as the huge chunk of ice dropped away and created a surge of water.
The kayakers, who operate the YouTube channels Steering South and Home With the Hoopers, wrote about their harrowing experience online.

"Andrew from Home With the Hoopers and I took a trip to Spencer Glacier for a one night camping and kayaking adventure. After setting up camp we hit the glacial lake for some awesome kayaking,"

"We made the 1.5 mile (2.4km) trek to the glacier and started hearing calving in the distance. We decided to investigate the noises and came face to face with one of nature's most awesome forces."
Bastyr added that it was one of the most intense things he ever witnessed and said they're both lucky to be alive.

A chunk of a glacier calved about 50 foot (15 metres) from us and created a 10-12 foot (3- 3.7 metre) wave. We were pelted with chunks of flying ice and buckets of water. To say we are lucky to be alive is an understatement," Hooper wrote on his channel.
"We learned our lesson and will give glaciers the space they deserve next time we are out exploring."
Spencer Glacier rises 1067 metres, and is located in the Chugach National Forest about 100km south of Anchorage. Read more here

Focas e as alterações climáticas : pausa férias





 via Google Images Archive



Agosto chegou. Tempo de férias. Em Portugal, bem como em muitos países da Europa, alunos e professores retemperam suas energias.

É tempo de fazer uma curta pausa, como já é usual. Prometemos voltar em Setembro!

Como sempre deixamos uma notícia ou fotografias de animais que nos chamam a atenção pela beleza ou, pelo contrário, pela tristeza que nos provocam. É caso desta postagem.


Segundo uma pesquisa, cientistas afirmam que as alterações climáticas na Antárctida fazem-se notar nas focas de pêlo.


Três décadas de dados científicos provam que as fêmeas desta espécie nascem menores, e as que sobrevivem à maternidade, estão produzindo mais tarde na vida. 


Mudanças subtis de ordem genética também estão sendo anotadas. 


Pesquisadores informaram o Nature journal que as alterações no padrão do clima dominante afectaram o principal alimento das focas -  pequenos crustáceos chamados krill.

"Nota-se que as focas estão sob grande stresse o que tem provocado redução significativa no tamanho e massa dos filhotes no nascimento", 

Dr. Jaume Forcada, British Antarctic Survey (BAS)


Isso está a provocar ainda que os filhotes que os filhotes tenham dificuldade em sobreviver à idade de reprodução.


Os pesquisadores descobriram que as focas no sul da Geórgia - norte da Península Antártica - parecem estar a sofrendo de uma redução da sua fonte de alimento - pequenos crustáceos chamados krill. Isso está causando os filhotes a nascer menores e de menos filhotes para sobreviver à idade de reprodução.

In Portugal, as in most European countries, August is school off. The students are on holidays. Teachers are on vacation as well. But not entirely. They are preparing their lessons for next school season.


We will be back in September! But first, here our holiday post.


Researchers from the British Antarctic Survey say environmental change is impacting on the survival of seals.´

Three decades of data show the females of this species are being born smaller, and those that do survive to motherhood are breeding later in life.

Subtle changes in their genetics are also being recorded.

Researchers tell the journal Nature that a shift in a dominant climate pattern has affected the supply of the seals' primary food source - krill.

"There has been a significant reduction in the size and the mass of the pups at birth," explained Dr Jaume Forcada from the British Antarctic Survey (BAS).



BAS has a seabird and seal biological research station on Bird Island

The researchers found that fur seals in South Georgia - north of the Antarctic Peninsula - appear to be suffering from a reduction in their food source - tiny crustaceans called krill. This is causing pups to be born smaller and for fewer pups to survive to breeding age.
The findings are published in the journal Nature.

Here, Dr Iain Staniland from the British Antarctic Survey explains how 30 years of studying the seals revealed the challenges they are facing.

Notícias bem tristes ! Focas com pêlo, mais uma espécie em perigo de extinção devido ao aquecimento global.

Boas férias ! Divirtam-se ! Voltamos em Setembro.

Ah! Não esqueçam de visitar o nosso blogue Geração Polar aqui 

Unfortunaly the news are sad ! Fur seals, another endangered specie due the climate change .


Please watch the video and pledge for fur seals in Antarctida !


Oh! By the way, please visit our blog Green Generation here


See you soon! On September! Have fun !
