Purpose
|
|
Map and sample groundwater discharge into near shore zone; map
|
|
suspended sediment concentration and grain size in water column; map benthic
|
|
cover.
|
|
|
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.

Got Help?
|
For A-5-03-HW, we would appreciate any information on -- analog materials, contract, days at sea, dive count, funding, kms of navigation, national plan, NGDC Info, notes, owner, project number, publications, scanned materials, seismic description, station count, station description, submersible, summary, tabulated info.
