A.T. Sediments

HideShow resource information
Lithogenous
Inorganic material derived from the weathering of coastal material.
1 of 21
Hydrogenous
Generated in situ chemically, either as coatings on lithogenous particles or as discrete phases.
2 of 21
Biogenic
Material generated biologically.
3 of 21
Anthropogenic
Sewage solids, fly ash, coal dust, paint particles.
4 of 21
Biodeposition
Biologically mediated deposition of particles.
5 of 21
Bioaccessibility
The availability to organism.
6 of 21
Biomimetry
Chemical or biological digestion extraction of sediment by representative reagents.
7 of 21
Plankton
Organisms that live in the water column that are too small or weak swimming to counter ocean currents, they are passive drifters.
8 of 21
Phytoplankton
Photosynthetic planktonic protistts and unicellular 'plantish' usually consist of single celled organisms or chains of cells.
9 of 21
Diatoms
Single celled eukaryotes cells encased in a silica dioxide shell made of 2 halves, no locomotion.
10 of 21
Dinoflagellates
Single celled eukaryotes, cells reinforced by armoured carbohydrate cellulose plates (can be unarmoured) with 2 flagella in grooves make cell spin and move vertically.
11 of 21
Zooplankton
Non-photosynthetic planktonic protists and animas ranging from single celled organisms to krill and larval fish.
12 of 21
Holoplankton
Plankton that spends it's hole life in the water column.
13 of 21
Meroplankton
Plankton that spends part of its life cycle in the water column usually larval stage.
14 of 21
DVM
Diel Vertical Migration - the largest migration on earth in terms of biomass, happens everyday.
15 of 21
Primary Productivity
Formation of energy rich compounds from inorganic materials to support the marine foodweb.
16 of 21
Microbial Loop
Loop that returns dissolved organic carbon into particulate food web, lots of microbes involving detritus, blood, dead phytoplankton and faeces.
17 of 21
Protist Nanozooplankton
Zooplankton that consume bacteria and nanophytoplankton which are preyed on by larger zooplankton and provides the link between pico and invertebrate zooplankton.
18 of 21
Marine Bacteria
Prokaryotic single celled organisms including autotrophs and hetertrophs.
19 of 21
Regime Shift
An unpredictable stepwise alteration in composition and productivity of whole ecosystem at a regional scale that reflects major hydrographic change.
20 of 21
HABs
Harmful Algal Blooms - algal phytoplankton, natural part of the ecosystem.
