Frustule
plankton skeleton
2 of 11
Photosynthetically active radiation
light of wavelengths 400-700nm
3 of 11
Compensation light intensity
light intensity required for rate of photosynthesis to match rate of respiration
4 of 11
Compensation depth
depth where rate of photosynthesis matches rate of respiration (lower boundary of euphoric zone)
5 of 11
Critical depth
depth where no photosynthesis occurs
6 of 11
Holoplankton
permanent plankton
7 of 11
Meroplankton
temporary plankton
8 of 11
Langmuir vortices
circulation consisting of a series of shallow, slow, counter-rotating vortices at the ocean's surface aligned with the wind. These circulations are developed when wind blows steadily over the sea surface.
9 of 11
Diel vertical migration
upwards migration of marine organism (response to light)
10 of 11
