Map and sample groundwater discharge into nearshore zone; map suspended sediment concentration and grain size in water column; map benthic cover.
Description
United States Geological Survey, Menlo Park, California,Stanford University. Chief Scientist: Mike Field. CTD and Video data (CTDmeter, opticalbackscattersensor, underwatertelevision, sizedistributionsensor, Niskenbottle) of field activity A-7-03-HW in West Maui, Hawaii from 07/05/2003 to 07/09/2003
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. _14C and _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.

A benthic habitat polygon coverage has been created of the coral reef ecosystem within the U.S. Coral Reef Task Force Watershed Partnership Initiative Kaanapali priority study area and the State of Hawaii Kahekili Herbivore Fisheries Management Area, West-Central Maui, Hawaii. Polygons were hand-digitized from visual interpretation of QuickBird-2 satellite imagery (2005), and SHOALS bathymetry data. We also utilized in situ knowledge from underwater photography and videography (2002-2011), side-scan sonar data, and diver and snorkeler observations. The polygons have attributes for Main Structure/Substrate, Dominant Structure/Substrate, Major Biological Cover, Percent of Major Biological Cover, Reef Zone, Unique ID, and measurements of Area (in square meters) of each polygon.
