Protistan metabolism across the western North Atlantic Ocean revealed through autonomous underwater profiling

Project description:An Autonomous Underwater Vehicle (AUV) and large volume underwater pumps were used to collect microbial biomass from offshore waters of the Sargasso Sea, from surface waters and into the deep ocean. Seawater collection was performed along a transect in the western North Atlantic Ocean beginning near Bermuda and ending off the coast of Massachusetts, capturing metabolic signatures from oligotrophic, continental margin, and productive coastal ecosystems.

The inhibition of N2O production by ocean acidification in cold temperate and polar waters

Project description:The effects of ocean acidification (OA) on nitrous oxide (N2O) production and on the community composition of ammonium oxidising archaea (AOA) were examined in the northern and southern sub-polar and polar Atlantic Ocean. Two research cruises were performed during June 2012 between the North Sea and Arctic Greenland and Barent Seas, and in January-February 2013 to the Antarctic Scotia Sea. Seven stations were occupied in all during which shipboard experimental manipulations of the carbonate chemistry were performed through additions of NaHCO3- + HCl in order to examine the impact of short- term (48 hour for N2O and between 96 and 168 hour for AOA) exposure to control and elevated conditions of OA. During each experiment, triplicate incubations were performed at ambient conditions and at 3 lowered levels of pH which varied between 0.06 and 0.4 units according to the total scale and which were targeted at CO2 partial pressures of ~500, 750 and 1000 μatm. The AOA assemblage in both Arctic and Antarctic regions was dominated by two major archetypes that represent the marine AOA clades most often detected in seawater. There were no significant changes in AOA assemblage composition between the beginning and end of the incubation experiments. N2O production was sensitive to decreasing pHT at all stations and decreased by between 2.4 and 44% with reduced pHT values of between 0.06 and 0.4. The reduction in N2O yield from nitrification was directly related to a decrease of between 28 and 67% in available NH3 as a result of the pH driven shift in the NH3:NH4+ equilibrium. The maximum reduction in N2O production at conditions projected for the end of the 21st century was estimated to be 0.82 Tg N y-1.

Candidatus pelagibacter ubique HTCC1062 requires 4-amino-5-hydroxymethyl-2-methylpyrimidine, an abundant thiamine precursor in the sea

Project description:Thiamine is often undetectable in ocean surface waters where Pelagibacter cells are numerically abundant. Despite this, Pelagibacter cells are missing de novo thiamine synthesis pathways. We show that an eogenous source of the thiamine precursor HMP is required for thiamine synthesis in Pelagibacter and that this precursor is abundant in the Sargasso sea. Batch cultures of P. ubique were grown in a defined arificial seawater media. Three cultures were given no thiamine amendment, and three other cultures received an excess concentration of thiamine. Cultures were harvested for microarray analyses just prior to and after thiamine limitation for the purpose of observing differences in gene expression related to thiamine limitation.

Purple sea urchin larvae alter their transcriptome in response to ocean acidification

Project description:In this research we present a transcriptomics analysis of the physiological response of a marine calcifier, Strongylocentrotus purpuratus, to ocean acidification, a decline in ocean pH that results from the absorption of anthropogenic carbon dioxide (CO2). Larvae were raised from fertilization to prism stage in seawater with elevated CO2 conditions based upon IPCC emissions scenario B1 (540ppm CO2) and A1FI (1020ppm CO2).
