GLOBEC NEP/CCS Mesoscale Planning (2002)
GLOBEC NEP/CCS Mesoscale sampling plan. (Revised from information provided by Jack Barth, OSU, 16 May 2002)
Here are the latest sampling grids for the mesoscale and fine-resolution
surveys. Click here to load a page with tables of waypoint coordinates in decimal degrees and degrees and minutes.
CCS Mesoscale survey
The mesoscale survey for the California Current System (CCS) region
spans from Newport, OR to Crescent City, CA. U.S. GLOBEC research
within this region in summer 2002 will occur on two cruises: 1)
late-May to mid-June, and 2) late-July to mid-August. The Seasoar
vessel will do an initial mesoscale survey (requiring about 6 days;
Figure 1) and a shorter, less complete survey at the conclusion of the
cruise. The initial survey will be sampled from north to south,
concluding on the Crescent City line. After the initial mesoscale
survey, there will be North and South fine-scale surveys (Figure 2) done as shown
in the next figure. Each fine-scale survey will take approximately 2
days. Fine-scale surveys will be done
from North to South (expected drifter trajectory). Currently, the
plan in May-June is to do the Northern fine-scale grid, then the
Southern fine-scale grid. The third figure shows the locations of the stations
along the Long-Term Observation Program (LTOP) transect lines. From
North to South the lines are designated as 1) Newport Hydro (NH), 2)
Heceta Head (HH), 3) Five Mile (FM), 4) Rogue River (RR), and 5)
Crescent City (CR). Each line is overlain by a Seasoar transect. Click here for a table of LTOP stations.
