Iceland 2016 (Sampling campaign in a lava-induced hydrothermal system in Iceland), July 17 – August 22, 2016.
Chief scientist: Christopher Hamilton (U. of Arizona)
Objectives: The Holuhraun eruption (2014–2015) generated a large flood lava flow, which inundated a segment of the Jökulsá á Fjöllum River, Iceland’s highest discharge river, resulting in unusual forms of hydrothermal activity. We sampled the glacier river close to its source (the Vatnajökull glacier) and at several downstream locations after the lava flow. We also conducted incubation experiments to complement our observations and test the effects of rapid water temperature fluctuations on microbial communities abundance, diversity and activity.

HOT200
HOT cruises (Hawaii Ocean Time-Series).
Objectives: Scientists working on the Hawaii Ocean Time-Series (HOT) program have been making repeated observations of the hydrography, chemistry and biology of the water column at a station north of Oahu, Hawaii since October 1988. The objective of this research is to provide a comprehensive description of the ocean at a site representative of the North Pacific subtropical gyre. Cruises are made approximately once per month to the deep-water Station ALOHA (A Long-Term Oligotrophic Habitat Assessment; 22° 45'N, 158° 00'W) located 100 km north of Oahu, Hawaii. Measurements of the thermohaline structure, water column chemistry, currents, optical properties, primary production, plankton community structure, and rates of particle export are made on each cruise.

Objectives: Study silicon cycling during the summer diatom bloom in the North Pacific Ocean.
BIOSOPE cruise (BIogeochemistry and Optics South Pacific Experiment), October-December 2004.
Chief scientists: Hervé Claustre, Antoine Sciandra (Paris 6 University)
Objectives: The main objective of the BIOSOPE project is to study, during austral summer, the biological, biogeochemical and optical characteristics of different trophic regimes in the South East Pacific, and especially the oligotrophic area associated to the central part of the South Pacific Gyre (SPG). The second objective of the project is to develop or adapt methods in order to be able to quantify stocks or fluxes at levels close to detection limits, which are expected to be encountered in the highly oligotrophic conditions associated to the SPG. The third objective of the project deals with a synthesis on the (biological, biogeochemical and optical) characteristics of various oligotrophic regime that have been studied (and will be studied here in the Pacific) as part of various JGOFS projects which were carried out during the last decade, in particular by the French community.
