As I have written about in an earlier post, the purpose of this research project, SALSEA-Merge, is to understand the life history of the Atlantic Salmon, and to the figure out why they are not returning to the river after their migration out of the rivers and into the sea. This expedition is seeking to [...]
With an early start to the day (0500), back up to the north, the CTD was in the water. The trawl was in and fishing by 0600 for a three hour tow. At 0900, the tow came up and was as expected with a nice concentration of post-smolts although they are quite small. The trawl [...]
One thing I find interesting on this cruise is that we only sample in so-called daytime hours. Despite the fact that we are above the Arctic Circle and have 24 hours of sunlight, the fish still sense the change in time of day. It is not the darkness that determines the fish behavior but the [...]
I arose to a beautiful calm morning on the North Atlantic with the Hebrides to the east of the ship. We are moving at quite a fast clip up to our sampling area, cruising at around 14 knots. We have a southerly wind behind us adding to our speed and the calm seas are helping [...]
A few months ago, Deirdre Brennan, a fellow member of the Explorers Club, approached me about a film, “Lost At Sea,” she is making with Eamon de Buitlear about Atlantic Salmon and where they go in the ocean once they leave the rivers. The ratio of fish leaving the rivers to those returning has [...]
After a bit of time on land, it is time for Gaelin and Global Ocean Exploration to head back out to sea. We will be embarking on the R/V Celtic Explorer departing from Killybegs, Ireland and heading north into the Norwegian Sea. Gaelin is honored to be carrying the Explorers Club Flag #81 on this [...]
