still water level

Earth science; Physical oceanography

The level of the sea with high frequency motions such as wind waves averaged out. See also mean sea level.

paradox of the plankton

Earth science; Physical oceanography

The long–term coexistence of plankton species that might be expected to compete. This is due to the degree to which chance encounters dictate the degree to which intra– or ...

lower low water (LLW)

Earth science; Physical oceanography

The lower of two low waters on a day when the tide is neither predominantly diurnal nor predominantly semidiurnal but rather intermediate to either (a situation sometimes called a ...

DMS-cloud-climate hypothesis

Earth science; Physical oceanography

The main source of sulfate particles and CCN over the oceans is the oxidation of DMS. As such the DMS may determine the concentrations and size spectra of cloud droplets and ...

chlorine titration

Earth science; Physical oceanography

The method developed by Knudsen and others in 1902 to determine the chlorinity and therefore salinity of a sea water sample.

California Coastal Ocean Observation System (CalCOOS)

Earth science; Physical oceanography

The mission of which is to provide an observation–based description of the resources of California’s coastal ocean in support of science, coastal resource management and emergency ...

detrital

Earth science; Physical oceanography

The most voluminous of three major components of deep sea sediments, the other two being authigenic and biogenic. Detrital material is derived from the mechanical and chemical ...
