AKA: none
Other ID: A-5-03-HW
Status: Completed
Organization(s): USGS, Pacific Coastal and Marine Science Center
Funding Program(s): Coral Reefs (MU070)
Principal Investigator(s): Michael Field
Affiliate Investigator(s):
Information Specialist(s): Eric Grossman, Ann Gibbs
Data Type(s): Environmental Data: CTD, Environmental Data: Turbidity, Imagery: Video, Sampling: Chemistry
Scientific Purpose/Goals: 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.
Vehicle(s):
Start Port/Location: Kaunakakai, Molokai
End Port/Location: Kaunakakai, Molokai
Start Date: 2003-07-10
End Date: 2003-07-13
Equipment Used: CTD, opticalbackscattersensor, underwatertelevision, transmissometer, Niskenbottle
Information to be 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.
