TL;DR: In this paper, data obtained during the monthly cruises of the DYFAMED time-series study (northwestern Mediterranean Sea) in the period 1995-2007 were compiled to examine the hydrological changes and the linked variation of some biogeochemical characteristics (nutrients and pigments).

TL;DR: Changes in phytoplankton composition and degradation of particulate organic matter (POM) in the northwestern Mediterranean Sea were studied using time-series sediment trap samples collected during the spring of 2003 at the DYFAMED station, and sterol degradation products appeared to be less suited than oxidation products of monounsaturated fatty acids for the precise monitoring of the degradation state of POM.

TL;DR: It is demonstrated that a complex array of biogeochemical parameters is the driving force behind bacterial community structure shifts in the water column, including phosphate, nitrate, salinity and to a lesser extent temperature, oxygen, dissolved organic carbon and photosynthetically active radiation.

TL;DR: In this article, the authors analyzed the sources and composition of thermally mature organic compounds in the East Pacific Rise at 13°N and found that they were derived from thermally altered microbial sources.

TL;DR: The free radical oxidation of long chain alkenones derived from haptophyte microalgae was studied in the laboratory in the presence of a radical initiator (di-tert-butyl nitroxide) and a radical enhancer (tertbutyl hydroperoxide).
