Similar glacial and Holocene Southern Ocean hydrography
We present new Holocene and glacial dO data measured on planktonic foraminifera Neogloboquadrina pachyderma and benthic foraminifera Cibicidoides species from the Atlantic and Pacific sectors of the Southern Ocean in order to better understand its glacial hydrography. Combined with previously published data, the latitudinal dO distributions of these foraminifera show no appreciable difference d...

متن کامل1 Obstruction Detection and Data Decimation for Airborne Laser Hydrography
Airborne lidar technology is attractive for hydrographic surveying because of its high rate of area coverage coupled with high spatial data density, rapid-response and reconnaissance capabilities, and cost effectiveness. The National Ocean Service (NOS) has been involved in the design, implementation, and testing of such systems in conjunction with NASA, the U.S. Navy, and the U.S. Army Corps o...
متن کاملThe population of Carassius gibelio (Bloch, 1782) and its parasites in Madatapa Lake (South Georgia)
