Seasonal Changes in Foraminiferal Flux and Shell Chemistry in the Northern North Atlantic

该项目将测量有孔虫的季节性 高纬度生产。 样本将在一个 北大西洋沉积物收集器的时间序列， 北大西洋现址附近的挪威-格陵兰海 深水编队。 两年的生产率记录， 壳层化学（稳定同位素）将与实时 地表水水文和化学观测， 校正古环境有孔虫记录 条件 %%% 北方的微生物外壳 大西洋和挪威-格陵兰海将被收集， 沉积物陷阱两年。 水的化学成分 在同一时间内测量。 结果将允许 研究人员校准这些水的现代化学成分， 有孔虫外壳的化学成分， 地质记录 这种校准很重要，因为研究 该地区是北大西洋深水形成的地点; 这些水团在气候历史上扮演着重要的角色， 地球

The project will measure the seasonality of foraminiferal production at high latitudes. The samples will be collected in a time-series of sediment traps in the North Atlantic and Norwegian-Greenland Sea near the present site of North Atlantic Deep Water formation. A two year record of productivity and shell chemistry (stable isotopes) will be compared to real-time observations of surface water hydrography and chemistry in order to calibrate the foraminiferal record of paleo-environmental conditions. %%% The shells of microscopic organisms in the northern North Atlantic and Norwegian-Greenland Seas will be collected with sediment traps for two years. The chemistry of the water will be measured during the same time period. The results will allow the researchers to calibrate the modern chemistry of these water with the chemistry of foraminiferal shells which are preserved in the geologic record. This calibration is important because the study area is the site of the formation of North Atlantic Deep Water; this water mass plays an importnat role in the climate history of the earth.
