Mark Moeller 10-28-08 Period 3 Chapter 7 Study Guide Barrier islands - long, thin, low offshore islands of sediment that generally run parallel to the shore along some coasts. Benthos - bottom-dwelling organisms. Coastal zone - warm, nutrient-rich, shallow part of the ocean that extends from the high-tide mark on land to the edge of a shelf like extension of continental landmass known as the continental shelf. Coral reef - formation produced by massive colonies containing billions of tiny coral animals, called polyps, that secrete a stony substance (calcium carbonate) around themselves for protection. When the corals die, their empty archer skeletons form layers and constantly to grow. They are found in the coastal zones of warm tropical and subtropical oceans. Estuary - partially enclosed coastal area at the Mac server where it's freshwater, carrying fertile silt and runoff from the land, mixes with salty seawater. Euphotic zone - upper layer of a body of water through which some might can penetrate and support photosynthesis. Eutrophication - physical, chemical, and biological changes that take place after a lake, estuary, or slow- flowing stream receives inputs of plant nutrients—mostly nitrates and phosphates—from natural erosion and runoff from the surrounding land basin. Floodplain - flat valley floor next to a stream channel. For legal purposes, the term often applies to any low area that has the potential for flooding, including certain coastal areas. Intertidal zone - the area of shoreline between low and high tides. Invertebrates - animals that have no backbones. Mangrove swamps - swamps found on the coastlines in warm tropical climates. They are dominated by mangrove trees, any of about 55 species of trees and shrubs that can live at a partly submerged in the salty environment of coastal swamps. Mesotrophic - having a moderate supply plant nutrients. Nekton - strongly swimming organisms found in aquatic systems. Oligotrophic - having a low supply of plant nutrients. Pelagic - refers to fish and animals that live in the open sea, away from the sea bottom. Phytoplankton - small, drifting plants, mostly algae and bacteria, found in aquatic ecosystems. Plankton - small plant organisms (phytoplankton) and animal organisms (phytoplankton) that float In aquatic ecosystems. Runoff - freshwater from precipitation and melting ice that flows on the Earth's surface into nearby streams, lakes, wetlands, and reservoirs. Thermocline –
