Summer oceanographic measurements near the Mertz Polynya (46-68S, 140-150E) on NATHANIEL B PALMER Cruise 00-08 from 2000-12-21 to 2001-01-19 (NCEI Accession 0001262)
This dataset includes physical and chemical oceanographic measurements along the George V Coast of East Antarctica, obtained during an early summer cruise of the Nathaniel B. Palmer. The primary scientific objective of NBP00-08 was to continue an investigation of shelf and bottom water formation, initiated by an Australian group in the winter of 1999 along a section of the continental shelf believed to be dominated by the large and persistent Mertz Polynya. Like many similar coastal features, the winter Mertz Polynya results from the combined influence of strong katabatic (gravity drainage) winds from the Antarctic Ice Sheet and a promontory, in this case the Mertz Glacier Tongue (MGT), which blocks the generally westward drift of sea ice along the coastline. This complementary summer cruise began on 20 December 2000 in Hobart, Tasmania, and ended there on 25 January 2001. More than 165 CTD/rosette casts were made in the 140-150E region south of 65S, roughly aligned in several north-south transects. Many stations were occupied within several hundred meters of the MGT, other grounded or floating icebergs, along the fast ice edge and in the drifting pack ice.
