Laurencia caspica (Red Seaweed) in the Caspian Sea

These are Red algae (Seaweed) in the south of Caspian Sea. I found in the Tonekabon Township one year ago. This species has not yet been identified. Iranian Researchers said they could not identified. They live on seashores and in the shallow waters of Caspian Sea. They are mainly found on wave-washed rocks (boulders) and underwater on the cobbles. This species is only found in west Tonekabon Township. Now, I posted them to Professor M.D. Guiry of Ireland

I'm Hope; they are new species in the south of Caspian Sea

Caspian Sea

The Caspian Sea is the biggest enclosed body of water on Earth, having an even larger area than that of the American Great Lakes or that of Lake Victoria in East Africa. It is situated where the South-Eastern Europe meets the Asian continent, between latitudes 47.07’N and 36.33N and longitudes 45.43 E and 54.20E. It is approximately 1,030 km long and its width ranges from 435 km to a minimum of 196 km. It has no connection to the world’s oceans and its surface level at the moment is around –26.5 m below MSL. At this level, its total coastline is some 7,000 km in length and its surface area is 386,400 km2. The water volume of the lake is about 78,700 km3. The water of the Caspian Sea is slightly saline; if we compare the Caspian water with oceanic water, it contains 3 times less salt.

What Is Environmental Sensitivity Index (ESI) Maps?

ESI maps provide a concise summary of coastal resources that are at risk if an oil spill occurs nearby. Examples of at-risk resources include biological resources (such as birds and shellfish beds), sensitive shorelines (such as marshes and tidal flats), and human-use resources (such as public beaches and parks). 

 

When an oil spill occurs, ESI maps can help responders meet one of the main response objectives: reducing the environmental consequences of the spill and the cleanup efforts. Additionally, ESI maps can be used by planners--before a spill happens--to identify vulnerable locations, establish protection priorities, and identify cleanup strategies.

Shorelines on ESI maps are color-coded by sensitivity to oil. Symbols mark localized areas for biological and human-use resources.
