Neritic Zone

Marine and Coastal Biomes

The neritic zone is the relatively shallow part of the ocean above the drop-off of the continental shelf, extending to a depth of about 200 meters. Sunlight reaches the ocean floor throughout the zone, keeping it within the photic zone where photosynthesis can occur, and its abundant light, well-oxygenated water and stable temperature and salinity make it exceptionally productive. These conditions let the neritic zone support the majority of the world's marine life and commercial fisheries through high primary production and complex food webs.

Facts

Climate

Typical Low Temperature (C)

-2 1

Same reasoning as the neritic zone high figure: shallow shelf water shares the polar surface freezing point already used for Open Ocean and Marine.

Typical High Temperature (C)

30 1

The neritic zone is the shallow, surface-connected water over the continental shelf, so it shares the same tropical surface temperature extreme as the Open Ocean and Marine biomes on the same source.

Annual Precipitation (mm)

990 2

Same global land+ocean blended figure and caveat used for Open Ocean and Marine; the neritic zone has no isolated shelf-water precipitation figure on an accessible source.

1. How Does the Temperature of Ocean Water Vary? (NOAA Ocean Exploration)

NOAA Ocean ExplorationIntroduction

Quote, Introduction

These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C (86°F) in the tropics to a very cold -2°C (28°F) near the poles.
