Concentration of inorganic nutrients, primary productivity measurements and phytoplankton cell concentration in seawater samples from the Malaspina 2010 Circumnavigation Expedition (VitaMaps project)
Abstract:
B vitamins (thiamin, B1; biotin B7; cobalamin, B12) are organic molecules necessary for all the biological transformations of the chemical elements that support life on Earth. Because most organisms lack the ability to synthesize several vitamins, their vitamin needs and environmental accessibility could define which, when, and where specific phytoplankton species flourish. Despite the early discovery of their relevance in the 1940s, most current marine vitamin research is still based on laboratory experiments or studies focusing on the biological responses of B vitamin additions on algae and bacteria. However, geographical distributions of B vitamins in the ocean are mostly unknown, as they have only been measured in a few marine basins.
This dataset contains B vitamin distribution measurements and ancillary (physical, chemical, and biological) parameters to elucidate the effects of vitamin availability on phytoplankton and bacteria species in surface waters of the world ocean collected during the Malaspina circumnavigation expedition. The different B vitamins were analyzed using a triple quadrupole mass spectrometer coupled to a liquid chromatography system after a solid-phase extraction with a C18 resin. This global map of vitamins is being used to determine the importance of dissolved B vitamins in microbial species biogeography, a still unresolved ecological riddle. Another objective of the study is to establish how ambient vitamin concentrations, combined with bioactive trace elements and macronutrients, promote changes in the relative abundance of different eukaryotic and prokaryotic plankton species on the surface ocean.
