As climate change causes the Arctic sea ice to recede, our ship Esperanza has sailed north of Svalbard to survey the poorly understood Arctic Ocean seabed. On the surface, the crew are observing and recording the diverse wildlife that has adapted to survive in this unique and harsh environment. Beneath the waves we are using a remote operated vehicle built and operated by top cameraman Gavin Newman to record the life on the sea bed in fine detail.

Greenpeace is calling for the area of the Arctic Ocean historically protected year round by sea ice to be closed to all industrial activity, including destructive fishing. Read more about the Arctic Under Pressure expedition.

I was gearing up to write something on the interesting new report by the New Economics Foundation (Nef) on how the EU is becoming more reliant on fish from other parts of the world, when my attention was drawn to a piece by the BBC's Richard Black who explains far more eloquently than I ever could what 'fish dependence day' is.

Nef has compared the amount of fish caught within the EU with the amount we consume to find out when - if we only ate our own, EU-caught fish from January 1 - we would have to start using fish supplied by other countries. This year, that day was last Friday 9 July or 'fish dependence day' and, like the global ecological debt day which Nef also computes, it's getting earlier each year as we import more and more fish. Or eat more. Or both.

Like I say, Mr Black covers all the main points and more on a sobering thought exercise. Read more »

Carlton Creek, who submitted a video to our HSBC advert challenge, has also produced this great little film which takes the ongoing discussions about attaching monetary worth to the natural services provided by our planet and turning them on their head. It's a neat little thought experiment into what the sales pitch for a company representing all life on Earth (or 'shareholders') would be like.

Elsewhere, artist and architect Maya Lin (previous work: Vietnam Veterans Memorial in Washington DC) is working on a collaborative, multi-media and multi-space project called What Is Missing? The current website highlights species which have been lost or are severely threatened, and if nothing else hovering your mouse over the map markers and hearing a soundscape of endangered creatures is haunting.

Karli Thomas, Greenpeace oceans campaigner, writes from the IWC meeting in Morocco.

The town of Sidi R'bat on Morocco's Atlantic coast is where the biblical Jonah is said to have been vomited up by a whale. Less than 100km from that spot, something has been going on this week that is again enough to make a whale sick to the stomach.

The International Whaling Commission has been meeting this year beneath a dark cloud of scandal. As delegates descended on the city of Agadir, media headlines exposed Japan 'buying' countries to vote with them - including the accusation that airfares and accommodation for this meeting's acting chairman were paid by Japan. Hardly an auspicious start to a crucial international meeting, nor a good omen for the whales. Read more »

Next week, our governments will get together in Agadir, Morocco, to talk whales. It’s the International Whaling Commission’s annual meeting. And this year, the main topic of conversation will be the IWC itself.

In reality, this is a testing time for the whales, and in many ways we need to make sure we save them all over again. Way back in the 80s when a moratorium, or ban, on commercial whaling was agreed, many countries had already stopped whaling. As the official catch figures show, by the time the ban came into force in 1987 commercial whaling was reduced to practically zero.

John Hocevar, team leader of the oceans campaign at Greenpeace USA, is currently in Louisiana helping with Greenpeace's response to the BP oil spill. Here's his latest report from the centre of the ever-growing disaster.

Greetings from Grand Isle, Louisiana, one of the growing number of places unlucky enough to win a "heavily oiled" classification on the government maps tracking the disaster in the Gulf of Mexico. Despite BP's efforts to keep it under wraps, we're here to document the impacts of the spill. The public has a right - and a responsibility - to know the true cost of our continued reliance on offshore oil, and fossil fuels in general. Read more »

Votes to support whaling are being bought by Japan in return for aid donations

So, what's your price to sell out the whales?

Some brown envelopes stuffed with cash? A nice big cheque for development aid? All-expenses paid trips to exotic locations? Or some dubious entertainment, including 'good girls'?

Welcome, dear friends, to the world of international diplomacy, Japanese government style. Yesterday, in a shocking expose, the Sunday Times showed the tawdry reality of Japan's vote-buying tactics to undermine the International Whaling Commission (IWC). Using undercover reporters, they managed to elicit scandalous accounts of just what the government of Japan offers to get the support of developing nations in the Caribbean, the Pacific, and Africa.

The crews of the Arctic Sunrise and the Rainbow Warrior have once more come to the aid of Atlantic bluefin tuna in the Mediterranean. Although the fishing season has ended early because the quotas have been reached, there are still large cages out there filled with fish caught over the past couple of weeks. These cages are bound for tuna 'ranches', where the fish will be kept and fattened up, before being slaughtered.

Yesterday afternoon our activists again tried to free the endangered tuna from one of these cages. Read more »

Greenpeace ships step in to stop bluefin tuna being fished to extinction © Hilton/Greenpeace

Today, or at 11.59pm tonight, to be exact, the purse-seining season for bluefin tuna in the Mediterranean is being closed. A week early.

I'm back on land now, having left the Arctic Sunrise in the Med. In London, we've had a flurry of media calls, excited by what they think is the "good news" that "bluefin fishing is being banned" in the Mediterranean.

So I thought, as well as putting the record straight with any journalists who'll listen, that I should maybe explain to everyone else what exactly is happening. And whether it is indeed "good news". Read more »

Like many other marine species, pteropods are threatened by ocean acidification © Cobbing/Greenpeace

Janet Cotter, from Greenpeace's Science Unit is currently on board the Esperanza on the first leg of the Arctic Under Pressure expedition. The ship is currently in Ny-Ålesund in the arctic, where Janet has been helping seagulls from 'contributing' to ocean acidification research.

In my day job, I work as a scientist as Greenpeace's Research Laboratories in Exeter, which is part of the Greenpeace's Science Unit. We might not get do the banner hanging from bridges and all the dramatic stuff that other Greenpeace activists do, but we have an important role in the organisation.  We analyse samples from around the world in our laboratories, often looking for toxic contamination of soils, rivers and seas, or sampling foodstuffs for GM contamination.
