under von Schleinitz circumnavigated the world and made many oceanographical observations particularly between Kerguelen and Mauritius. In
Montevideo, incidentally, the Gazelle and the Challenger met, and their
homeward courses were arranged to ensure the best possible coverage of the
Atlantic Ocean.
gelatin water-soluble protein, yielded by hydrolysis of collagen (protein of connective tissue in animals).
Gelbstoff (syn. yellow substance) term introduced by K. Kalle (~fluorescence), who
noted the absorption of light in the blue part of the absorption spectrum of
both sea- and freshwater containing much dissolved organic matter
(~carbon, organic), resulting in yellow water. Gelbstoff is often used as a synonym of persistent substances, but this has neither a quantitative, nor a qualitative value. Related to humic acids and mainly transported to sea by land runoff. Gelbstoff can be used as a tracer of river water in estuaries and the sea.
generation time ~population dynamics.
geobiocoenosis ~biogeocoenosis.
geochemical cycle for a given chemical element or compound its distribution
and transport over the surface of the earth can be described in a mass balance approach. Typical reservoirs are the continental crust, continental sedimentary rocks, freshwaters, seawater, the atmosphere, the continental and
marine biosphere, deep-sea sediments and Mid-Ocean Ridge Basalts, etc.
Fluxes (mol y-l, Gtons y-l) between reservoirs are quantified in rate terms of
weathering, river transport, estuarine removal, seawater input and removal,
evaporation, precipitation, sedimentation, submarine hydrothermal weathering, etc. For a given reservoir the ratio of its size and its overall throughput
(fluxes) yields the characteristic residence time. The residence time of a chemical element in the ocean may vary from about a decade to millions of years.
geochronology measurement of geologic time, either in absolute age or in relative
age (~geological time scale and ~stratigraphic hierarchy).
geoid (syn. geopotential surface) the theoretical (equipotential) surface of the
earth which is everywhere perpendicular to the direction of gravity (the
plumb line). It can be considered a mean sea-level surface extended continuously through the continents. If the oceans were everywhere at rest the
ocean surface would be a geopotential surface.
geological time scale scale of relative time. The division is based on biostratigraphic and lithostratigraphic characteristics. Names used here (see figure)
