Transcript of The Open Ocean

The Open Ocean Biome
The Open Ocean
-Atlantic Ocean
-Pacific Ocean(largest biome)
-Indian Ocean
-Southern Ocean
-Arctic Ocean
-The average temperature is 39 degrees
-Warm water from tropics
-Cold water from poles
-Water near the polar regions is colder than water near the equator
-Sunlight breaks through the top layer of the ocean as deep as 200 meters

APES 4th hour
Three vertical zones
-Euphotic zone

-Bathyal zone

-Abyssal zone
Euphotic Zone
-Phytoplankton: plant like
-Nektons(strong swimmers): fish, turtles, whales etc.
-Temperature: warm
-Nutrients levels are low
-Dissolved oxygen levels are high

Bathyal Zone
*primary and secondary consumers
*single-celled to large invertebrates like jellyfish
-Top is warmer
-Bottom is cooler
-Dimly lit
Abyssal Zone
-Deepest part of the ocean.
-Depths of 13,123 to 19,685 feet
-Dark and cold
-High levels of nutrients
-Little dissolved oxygen
-Filter feeders
-Bacteria and invertebrate creatures are found in this zone.
-Oysters, sea stars, clams, lobsters, and crabs.

Importance to Humans
-Removing carbon from the atmosphere and providing oxygen. (Kelp and phytoplankton 50%)

-Regulates earth's climates.

-Biomedical organisms with enormous potential for fighting diseases.
Environmental Concerns
*Trash, sewage, and chemicals
*Millions are dumped every year.
-Oil Spills
-Animals die by eating plastic bags by mistaking them as jelly fish.
-Fishing is a global problem.
-6,100 tons fish caught every year.
Fun Facts
-90% of the ocean is dark and reaches no sunlight.

-More salty in tropical areas because the sun evaporates
more water leaving more salt in the ocean.

-Largest biome on earth.

-it covers 70% of the planets surface.

-Salt comes from rocks on land that gets swept into the ocean.

-One cup of salt for every gallon of water in the ocean.

-The Mariana trench is the deepest part. 36,200 feet deep.

-Largest mammal is the blue whale.

-Shrimp-producer and consumer
-Sharks-Alpha predator
-Sea otters[Producer
Food Web
-Starfish-primary and secondary consumer
-Shrimp-producer and consumer
-Sharks-Alpha predator
-Sea otters-Producer
-Air temperature
-Water temperature
-Atmospheric Pressure
Grass, seaweed, and algae are primary producers that get eaten by the eastern green turtles, fish, and mussels and they are primary consumers. The Primary and secondary consumers is the sea star that eats algae but gets eaten by mussels. The killer whales, dolphins, and great white sharks eat the primary consumers. The killer whale and great white shark are tertiary consumers and dolphins are secondary consumers because they get eaten by the killer whale. Nitrobacter winogradski is a decomposer.
Station 44013 (LLNR 420) - BOSTON 16 NM East of Boston, MA
Boston Approach Lighted Buoy BF NOAA 44013
Owned and maintained by National Data Buoy Center
3-meter discus buoy
ARES 4.4 payload

Site elevation: sea level
Air temp height: 4 m above site elevation
Anemometer height: 5 m above site elevation
Barometer elevation: sea level
Sea temp depth: 0.6 m below site elevation
Water depth: 64.5 m
Watch circle radius: 124 yards
Caution: Right whales may be active in northeast waters year-round. Mandatory speed restrictions of 10 knots apply to vessels 65 feet or greater in specific areas and times along the US east coast. Voluntary speed restrictions may be in effect in other areas and times. For current information on speed-restricted areas, go to:
