Map and sample groundwater discharge into near shore zone; map suspended sediment concentration and grain size in water column; map benthic cover. Acquire underwater video.
Description
United States Geological Survey, Menlo Park, California. Chief Scientist: Mike Field. CTD and Video data (CTDmeter, opticalbackscattersensor, underwatertelevision, transmissometer, Niskenbottle) of field activity A-5-03-HW in Molokai, Hawaii from 07/10/2003 to 07/13/2003
Location
Hawaii
Info derived
Conductivity, temperature salinity, optical backscatter, sediment concentration and 32 sediment-grain size classes of suspended sediments, pH, and chlorophyll in the water column. Scaled video of substrate type, coral cover, and benthic habitats. Ra isotopes of nearshore water to derive mixing models and quantify terrestrial groundwater discharge into near shore. Delta-14C and isotope-13C of near shore waters to quantify terrestrial groundwater discharge into near shore. DIC concentration of near shore water to quantify carbonate chemistry. DOC and POC of near shore water to assess local carbon budget. Nutrient concentration (nitrate, nitrite, ammonium, phosphate) of near shore water to characterize nutrient and calculate flux.
