Flashcards in Chapter 16: Marine and Coastal Systems and Resources Deck (14):
1

Trawling

Dragging net across ground

2

Pycnocline

Area where density rapidly increases with depth

3

Upwelling

Cold, deep waters pulled to the surface. Nutrient rich

4

Downwelling

Surface currents converge, so water sinks. Influx of oxygen and 'buries' CO2

5

Thermohaline circulation

Worldwide current system in which warmer, fresher water moves along the surface and colder, saltier water moves deep beneath the surface

6

Photic zone

Where almost all of ocean's primary productivity occurs

7

Pelagic

Life between ocean surface and floor

8

Benthic

Life on ocean floor

9

Intertidal/Littoral

Ocean meets land

10

Tides

Periodic rising and falling of the ocean's height at a given location caused by gravitational pull of moon and sun

11

Zone areas (top to bottom)

Supratidal zone (Splash zone), Lvel of high tide, intertidal, level of low, subtidal

12

Salt marshes

Where tides wash over gently sloping sandy or silty substrates

13

Estuary

Rivers flow into ocean

14

Coral reef

Mass of calcium carbonate composed of the skeletons of tiny marine animals known as corals
