DEFINITIONS

cleavage
: The successive cell divisions of a fertilized egg of an animal to form a multicellular blastula.
dioecious
Etymology: ultimately from Greek di- + oikos
1 : having male reproductive organs in one individual and female in another
2 : having staminate and pistillate flowers borne on different individuals
deuterostome
Etymology:Gk. deuteros, second + stoma, mouth
: An animal in which the anus forms at or near the blastopore in the developing embryo and the mouth forms secondarily elsewhere; echinoderms, hemichordates, chordates, and chaetognaths are deuterostomes. Deuterostomes are also characterized by radial cleavage during the earliest stages of development and by enterocoelous formation of the coelom.
Force 5 Seas
: taken from the Beaufort Scale with Corresponding Sea State Codes - Knots:17-21; Mph:19-24; Meters per second:8.0-10.7; Km per hour:29-38; Seaman's terms:Fresh Breeze; Effects observed @sea:Moderate waves; taking longer form, many whitecaps, some spray; Effects observed on land:Small trees in leaf begin to sway
Gulf Stream
A warm, well-defined, swift, and relatively narrow ocean current that originates north of Grand Bahama Island where the Florida Current and the Antilles Current meet. The Gulf Stream extends to the Grand Banks at about 40°N, 50°W where it meets the cold Labrador Current, and the two flow eastward as the North Atlantic Current.
holoplankton
: organisms which persist as plankton throughout their entire life history.
meroplankton
: floating eggs or larvae of organisms that will assume a nektonic (free swimming) or benthic (sediment-associated) existence in their adult stage; temporary plankton.
microplankton
Etymology: International Scientific Vocabulary
: microscopic plankton
monoecious
Etymology: ultimately from Greek mon- + oikos house
1 : having pistillate and staminate flowers on the same plant
2 : having male and female sex organs in the same individual : HERMAPHRODITIC
nanoplankton
Etymology: New Latin, from Greek nanos, nannos dwarf + New Latin plankton
plankton
: small plankton that consists of those organisms (as bacteria) passing through nets of very fine mesh, or within the size range of 0.005-0.075 mm.
neoteny
Etymology: New Latin neotenia, from ne- new + Greek teinein to stretch, Latin tenuis thin, tenEre to hold, tendere to stretch
1 : retention of some larval or immature characters in adulthood
2 : attainment of sexual maturity during the larval stage
paedogenesis
Etymology: New Latin
: reproduction by young or larval animals; capable of maturing gonads and reproducing in the larval stage
paedomorphosis
Etymology: New Latin, from paed- + Greek morphOsis formation, from morphoun to form, from morphE form
: phylogenetic change that involves retention of juvenile characters by the adult
paedomorphic
: of, relating to, or involving paedomorphosis or paedomorphism
Main Entry: paedomorphism
: retention in the adult of infantile or juvenile characters
plankton
Etymology: German, from Greek, neuter of planktos drifting, from plazesthai to wander, drift, middle voice of plazein to drive astray; akin to Latin plangere to strike
: the passively floating or weakly swimming usually minute animal and plant life of a body of water
province
: a biogeographic division of less rank than a region b : an area that exhibits essential continuity of geological history; also : one characterized by particular structural or petrological features
pycnocline
: a zone of rapid water density change; the lowest densities are usually found in warmer surface waters, and highest densities in colder, deep water.
seta
Inflected Form(s): plural se·tae /'sE-"tE/
Etymology: New Latin, from Latin saeta, seta bristle
: a slender usually rigid or bristly and springy organ or part of an animal or plant
thermocline
: a thermocline is an area of change in density and/or temperature with depth

upwelling
: The process by which water rises from a lower to a higher depth, usually as a result of divergence and offshore currents. It exerts a distinct climatogenetic influence by bring colder water to the surface. The upwelled water, beside being cooler, is richer in nutrients, so that regions of upwelling are also regions of rich fisheries.
