Philippe Koubbi. Correspondent aboard the Umitaka Maru

(written with Patrice Pruvost)
As you know from preceding dispatches, the Umitaka Maru is a veritable floating laboratory. At each station, all the scientists on board wait impatiently for the samples to get at the materiel needed for their research.

Watch out for swells!

Patrice Pruvost. Correspondent aboard the Umitaka Maru

The day is calm. We are now well into the Southern Ocean. We are moving at 15 knots. Starting in the middle of the night, the sea was hitting us abeam. The waves hitting the side of the ship made us roll from one side to the other.

The "Fish Team" of the Umitaka Maru wishes you a happy Valentine’s Day. We are delighted at the idea of soon being back with our families after six weeks of being so far away from them. Despite the superb places we have enjoyed during our campaigns, we remember that our families are taking care of daily life at home.

Return to deep water!

Patrice Pruvost. Correspondent aboard the Umitaka Maru

There is no doubt! This time we have crossed the hydrological front that separates the waters of the continental plateau from those of the open sea. Albatrosses fly around the ship. Some species among them nest on the subAntarctic islands.

We arrive at the furthest south position of the trip. We are near Mertz glacier, which must measure nearly 200 km long. Every year, huge blocks of ice detach from it forming icebergs that drift off.

How to survive in cold water

Philippe Koubbi. Correspondent aboard the Umitaka Maru

(Written By Eric Tavernier)
The polar regions are marked by strong seasonal variability: summer is short, with a lot of light, warming surface waters and massive primary production (phytoplankton); winter is characterized by months-long darkness and little food.

The larval phase of teleost fish is a development stage of prime importance for populations because of its sensitivity to environmental changes such as climate or food fluctuations on which their survival depends.

Moments of anguish!

Philippe Koubbi. Correspondent aboard the Umitaka Maru

(Excerpt from the log of Jean-Henri Hecq)
09h30. We are approaching the DDU base. There is excitement on board! They have unrolled the red carpet at the entrance to ship. The cadets come ask us how to pronounce "bonjour," "bienvenue á bord," "bonjour mademoiselle," "enchanté de vous recevoir" in order to greet the French on the Umitaka Maru. We sail at 2 knots in the icebergs. The maneuver is dangerous with the stormy sea, violent wind and snow and visibility of scarcely 200m.

Patrice Pruvost. Correspondent aboard the Umitaka Maru

We are in the middle of the ocean, in the middle of nowhere! We have been surrounded by ocean for several days now! Still, each day on the ship seems very different from the one before. Certainly this feeling comes from the changes in light, in weather and in the sea.
