Summary:
In accordance with the research plan outlined in our original proposal, we began monitoring indicators of plankton production (Chl-a, cell counts) in surface waters of Long Island Sound from the Port Jefferson / Bridgeport Ferry on Dec. 3, 1992. In contrast to past years no dramatic bloom has occurred to date although a significant pattern of increasing chl-a began during the first week of April. We anticipate that the bloom wig be complete by mid to late April. This has been a particularly cold year based on comparison of 1993 bottom water temperatures and previously reported patterns from LIS, possibly reflecting climatic conditions which delayed the bloom. Typical sampling includes: surface and bottom water sampling for suspended matter, cell counts, chlorophyll-a, nutrients; triplicate box cores for macro-, meio-, and microfauna analysis; subcores for O[sub 2] microelectrode profiles; box core for radiochemical analyses ([sup 234]Th, [sup 7]Be); box core subcores for benthic fluxes under aerated and nonaerated conditions (O[sub 2], [Sigma]N, Mn[sup ++], [Sigma]CO[sub 2]); Br[sup [minus]] tracer flux core incubation for biogenic irrigation rates; box core for laboratory based luminophore tracer experiments (particle mixing); box core subcores for solid phase and pore water solute profiles (carbonate system, nutrients, Ca, Mg, Sr, F, Mn, Fe) at 0.25 [minus] 1 cm intervals; and box core subcores for chloropigment profiles and reaction rate incubation experiments.
