NOAA NOAA Learning Ocean Science through Learning Ocean Science through Ocean Exploration Ocean Exploration CurriculumCurriculum

Doing Inquiry-based Science with Students:

•Direct observation

•Manipulate variables under natural conditions

•Use model systems which can be manipulated in the classroom

•Learning Ocean Science through Ocean Exploration of necessity concentrates on using model systems.

•Essential that students understand the relationship between the model and the real thing. OE website gives them access to the real thing.

Ocean ZonesOcean Zones Many abiotic factors contribute to zonation in the ocean: vertical and horizontal components• pressure, light, temperature, salinity, dissolved

oxygen, mineral nutrients

Vertical zonation is featured in the OE curriculum. • Examines light and the impact passing through

water has on light in the ocean.• photic or epipelagic (0 - 200m)• mid-water or mesopelagic (200 - 1000m)• aphotic or bathypelagic (below 1000 m)

Light Zones in the OceanLight Zones in the Ocean

PHOTIC/SUNLIGHT ZONE – 200 m.

Plants thrive, food relatively abundant

DYSPHOTIC/TWILIGHT ZONE – 1000 m

Dim light can not support plants, reduced food (20% of photic zone production), temps. 23 >> 4 degree C . (thermocline)

APHOTIC/MIDNIGHT ZONE-below 1000 m Perpetual darkness, only 5% of photic zone food production, 4 degree C. temp

Light at the Bottom of the Deep Dark OceanLight at the Bottom of the Deep Dark Ocean

If you drag a net out in the open ocean from 1000 m to the surface, 80 to 90% of the animals caught (mostly fish, shrimp and squid) will be bioluminescent. That doesn't include all the bioluminescent jellyfish that get shredded by the net.
