Marine Ecology: 2/25/19 Its not like I wanted to consume the Phytoplankton! B-baka! Processes, Systums, and Impacts. Pelagic = "of the Open Sea" •Anthropogenic Impacts. •99.5% of Earth's inhabitable space. Outside of Neritic zone. Depths: Mesopelagic = 200-2K Bathylpelagic 2K 4K - Abyssal pelagic = 4k 4k Neustic zone = Above Photic Zone. Planktonic = "passive Swimmers" Nekton = "Active swimmers" Prytoplankton need sunlight, so they'll be e <200 m zooplankton = categorized by size. Meroplankton = spend earlier life stage as plankton. Holoplankton spend ENTIRE life as plankton. Diel Vertical Migration = Nocturnal, Reverse, Twilight Phytoplankton die and become Marine Snow. They'll decompose by bacteria. Primary Producer biomass could be used to predict. Future biomass. Salinity has a higher influence on density than temp. Henry Stommel: developed Stommel diagram. Illustrates Time/Space variations of plankton. Biomass of higher trophic levels. 2/27/19 ubiqutous = abundant everywhere. Diel vertical migration occurs. reasons. due to many different * Physical Properties Contributing to Temporal * Pycnocline layering trend due to salinity & Temperature. Langmuir Circulation. wind-driven upwelling. above the thermocline. R 0000 •"wind lanes" Coriolis Effect: movement based gravity on the variability of Eckmon Transport and Spiral. Primary Production interferes with the abundance of Higher Trophic Levels. Regime shifts in the Ocean. kelp us Seaweed 11 Coused a shift in the ecosystem.
