|---|
.5 - 1 million species estimated; Macroscopic - mostly billfishes, cetaceans (whales, dolphins, porpoises), seabirds, sharks, and tunas Microscopic - mostly planktons (phytoplankton \[photosynthesis-dependent\], zooplankton, baceteriaplakton Deep sea coral reefs support "diverse assemblages of marine life" |
B. Fished Species
Concentrate effort on finding effects on climate change for these:
Atlantic
Roundnouse Grenadier (Coryphaenoides rupestris, Macrouridae)
Alfonsinos
ling (Molva molva, Lotidae)
blue ling (M. dypterygia, Lotidae)
tusk (Brosme brosme, Lotidae)
roughy
bulls-eye (Epigonus telescopus,Epigonidae)
deepwater sharks (Centroscymnus coelolepis,Dalatiidae)
Dalatias licha, Dalatiidae;
Centrophorus squamosus, Centrophoridae);
Deania calcea,Centrophoridae)
Deep-sea fishing here has emerged after 1989 and is sharply increasing.
Pacific
dover sole (Microstomus pacificus, Pleuronectidae),
...
Deep-sea fishing here has been in place since 1900 and increased from 1950-1959
Indian Ocean
Rexea solandri,
orange roughy and
Patagonian toothfish (Dissostichus
eleginoides, Nototheniidae)s
Deep-sea fishing here has emerged after 1989 and continues to continue at an increasing rate
Antarctic Ocean
other Nototheniidae species
marble rockcod (Notothenia rossii, Nototheniidae)
Most dramatic increase in fish depth, occurring since the 1960's and continuing
Southern Ocean fish are highly adapted to cold water via low metabolism and the reduced use of red blood cells due to high oxygen solubility.
Isolated from usual temperature variations by Antarctic Circumpolar Current
C. Effects of Projected Climate Change
Increased ultraviolet radiation due to ozone
depletion harms microscopic, photosynthetic
algae and zooplankton at the base of the oceanic
food web, potentially affecting the food supply
of the entire marine community.

Current changes (see attached file by Juliana) disrupt normal heat distribution, displacing/killing creatures
