Tidal Pools. Found on rocky coasts Depressions in rocks that hold seawater Formed when tide goes out . Formation. Abiotic Conditions. Less water in pools than ocean During low tide, no water enters = great change Greater extremes of temperature & salinity Temps rise up to 15 o C

  1. Tidal Pools

  2. Found on rocky coasts Depressions in rocks that hold seawater Formed when tide goes out Formation

  3. Abiotic Conditions • Less water in pools than ocean • During low tide, no water enters = great change • Greater extremes of temperature & salinity • Temps rise up to 15oC • Salinity 35 – 45 ppm

  4. Waste products build up in pool • N-containing compounds • CO2 from respiration • Increase in acidity due to CO2 build up • Returning tide restores normal conditions • Wastes washed away • Plankton & nutrients come in • Salinity, temp, and pH normalize • WAVE SHOCK!!

  5. Organisms of Tidal Pools • Producers • Fish Coralline algae Spongeweed Red algae Sculpins Blenny Opaleyes

  6. Invertebrates
