FIRST YEAR WORK

We plan to continue and expand our previously funded LTOP program to make seasonal cruises (five per year), adding cross-margin sections off Crescent City and Eureka on all spring, summer and autumn cruises beginning in April 2000. We plan to make additional cross-margin sections at two additional sites on LTOP cruises during the two GLOBEC intensive field studies in the California Curren t system (2000 and 2002). We plan to continue regular drifter deployments, and to maintain the current meter mooring over the shelf off Newport. Zooplankton sampling will be expanded with MOCNESS tows and towed high-frequency acoustics.

We are curren tly funded (under "Long-Term Observations off Oregon for Climate Change Studies in the Eastern North Pacific", NA86OP0589) to make seasonal LTOP cruises in 1999 and 2000, with physical and biological sampling along two cross-margin sections (off Newport a nd Coos Bay, OR) until 31 August 2000; with those funds we will make three cruises in 2000. We request new funds for two additional LTOP cruises in 2000 (September and November), and to expand the observational program to include sections off Crescent Cit y (41.9°N) and Eureka (40.9°N) on the April, June and September LTOP cruises in 2000. We also request funds for sampling along two special sections (at Heceta Bank, 44°00'N, and Rogue River, 42°30'N) on LTOP cruises which occur in the April through September period of the intensive field year. Sampling on all lines will include underway sampling of wind speed and direction, water velocity to a depth of 400 m, surface temperature, surface salinity, surface fluorescence and acoustical es timates of zooplankton biomass, and on-station water-column sampling of temperature, salinity, oxygen, fluorescence, light transmission, nutrients, chlorophyll and zooplankton. New funds are also requested for recovering and redeploying the current meter mooring at NH-10 over the continental shelf off Newport.
