Salt Marsh 2012
Transcript of Salt Marsh 2012
Long Island's South Shore Outwash Coastal Zone
Major Zones in a Marine Ecosystem
Long Island Estuaries:
Great South Bay
Long Island Sound
Estuaries & Tidal Ecosystems
Supratidal mark to the continental shelf
Warm, nutrient-rich shallow water
Supports 90% of all marine ecosystems
Types of Salt Water Life Zones:
Estuaries & Tidal Zones
"An estuary is a semi-enclosed coastal body of water that extends to the effective limit of tidal influence, within which sea water entering from one or more free connections with the open sea, or any other saline coastal body of water derived from land drainage, and can sustain euryhaline biological species from either part or the whole of their life cycle." (Perillo, 1995)
What is an Estuary?
GREAT SOUTH BAY ESTUARY
Long Island Sound Estuary
Coastal Zone Salt Marshes
Since 1900, the world has lost more than ½ of it’s coastal wetlands.
75 % of the world population lives in the coastal zone (high tide – continental shelf)
Salt marshes and littoral zone support greatest net primary productivity for coastal environments.
Net primary productivity in the ocean is very low, BUT because it covers over 70% of Earth’s surface, COLLECTIVELY it makes the largest contribution to the Earth’s overall net primary productivity

SALT MARSH FOOD WEB
1. Learn more about estuaries.
2. Keep septic systems working properly. Pump your system every three years.
3. Pave less. Hard surfaces hasten runoff and increase pollution and erosion.
4. Adhere to "no-wake" zones when on your boat. Waves destroy shorelines and increase erosion.
5. Think before you pour. Many hazardous products flow from household drains through sewage treatment plants and into coastal bodies of water.
6. Fish respectfully. Follow "catch and release" practices and keep more fish alive.
7. Create non-toxic pesticides. A bit of soap and water does the job and keeps harmful chemicals from ending up in nearby waterways.
8. Use native plants. Garden and landscape with plants native to your area to reduce the need for watering and fertilizing.
9. Respect habitat. Treat the homes of vital marine life with care. Habitat and survival go hand-in-hand. When habitat disappears, so do many plants and animals.
10. Take action! Organize a stream or beach cleanup. Encourage your local newspaper to write a story, or ask an expert to speak at your community organization or local school.
