A breathing ocean

A group from the Uni Bjerknes Centre and the Bjerknes Centre for Climate Research in Bergen, Norway, are on-board to perform measurements related to the oceanic cycling of carbon, in addition to measurements estimating the flux of oxygen directly involved in biological activity.

The parameters describing the oceanic carbon cycle include total inorganic carbon dissolved in the seawater (DIC), total alkalinity, pH, and the partial pressure of CO2 (pCO2).

The Video Plankton Recorder (VPR) is non-destructive modern, optical sampling gear. Imagine flying a sophisticated underwater microscope through the water at night. The VPR`s rapid camera images plankton and suspended particles (the base of the food web) at up to 30 frames per second.

After a successful first leg we arrived in Torshavn (Faroe Islands) early morning on last thursday (5 April). Most of us invaded the town right way, eager to set their feed on land and to interact with civilization outside our tiny microcosm universe.

Surface Blooms as convection goes strong

Following a short stop at Torshavn (Faroe Islands) last weekend for a crew swap, the FS METEOR is back in the sampling area in occassional heavy seas.

Due to a problem, 24hrs were lost from the schedule, but the team is now trying to catch up. Seniour scientist aboard, Michael St John, mentions that the surface has not yet stratified, but FS METEOR is sailing in surface bloom conditions.

“Convection is still spinning out here. Amazing!!” Continue reading

Snow above, snow below

by Ivo Grigorov, EURO-BASIN Project Office

While waiting for the expedition to change over the scientific party before heading back out to sea, how about an imaginary journey. Imagine you had James Cameron`s DEEPSEA CHALLENGER submersible for a day, and you were descending down just below the FS Meteor in the Faroe-Shetland Channel. What would you see?

Greetings from Meteor docked in Thorshavn, Faroe Islands. Here we are just finishing off our first circuit around the triangle. The weather gods have been relatively friendly, we have missed but a few hours due to rough seas which is rather surprising. To give you an idea, last night we had snow on the deck leading some to test their snowball skills, but again, no big seas.

The night before we took a wave over the back deck that twisted the big metal frame of the MOCNESS. The power of water is truly amazing! It seems every time we get close to the side of the boat, Neptune has a greeting for us. This is now an expected by all on board. I guess he does not want to give up his secrets without a comment or two. Anyway, we can hope for more friendly weather for the next leg, but as we all know this can be a stormy time of the year.

Laser counting in bouncy seas

Over the last 48 hours we have crossed the Faroe-Shetland Channel, and are relatively sheltered by the Shetland Islands to the west of us.

Waves crashing over the side is a regular event while sampling the North Atlantic.

MOCNESS ‘monster’ released over the stern

Zooplankton drift passively with the currents, and although most are less than 2 cm in size, their grazing on marine algae transfers significant amounts of carbon away from the surface, and contact with the atmosphere.

On this cruise we are aiming to pinpoint at what depth zooplankton concentrate, while waiting for the spring bloom to occur.

Our tool of choice is a Double-MOCNESS (Multiple Opening and Closing Net and Environmental Sensing System): a net system with 2 x 9 nets of 333 μm mesh size and a net mouth opening of 1m2.
