Today was an odd day. A few days ago, we published the news that we had located about a dozen dead seals near the Bogskär lighthouse (Åland Island). This news was widely picked up by the media, and some countries are interested in finding out the cause of these deaths. For this reason, we returned to the area together with Åland Island Coastguards.

As we sailed south, water temperature rose. Now we are on parallel 60. We have come down from parallel 65, the latitude of central Alaska, northern Iceland, and the Bering Strait, all very cold areas. These days, water temperature has risen to a “warm” 4ºC, almost 4 degrees more than in the North.

The days go by with our expedition activities. Scuba diving on waters shallower than 20 meters, ROV operations with the “Hanse Explorer” on anchor up to 50 m, and drifting with the ROV when in deeper waters down to the bottom this northern part of the Bothnian Sea. 160 meters are the largest deeps in this area.

After a brief morning meeting, we went out in the Zodiac's to dive two different locations.
The locations are within an area Finland is planning to make into a MPA (Marine Protected Area). The findings of the dives will be reported to the Finish government to help with their assessment of the area.

Today I got up, like most days, at 8 in the morning, after a night in which sunlight woke me up at around 5. Funny, isn’t it? Days here are so long that they almost make the night disappear.
Today we will be performing several study methods: trawl, CTD, ROV and diving. We will be exploring various depths and ecosystems.
We are in the northern area of the Bothnia Gulf, were waters are calmer and the salinity drops to limits that few marine species can bear. Biodiversity is highly reduced here, and we hardly found any fish of commercial interest.

We woke up in Sweden on parallel 63º, and we still must sail farther north. The first ROVs were carried out at 220 m deep, in brown water that is rather reminiscent of that found in rivers and reservoirs. We have also taken samples using the trawl and the CTD.
We arrived in the harbour of Mariehamn in the morning, after having passed tens of smaller islands. Mariehamn is the capital of Åland Islands, which is an autonomous Swedish-speaking territory under Finland. Åland Islands consists of thousands of islands, situated at the entrance to the Gulf of Bothnia.
