Corals depend on symbiotic algae to survive and build coral reefs. Increased ocean temperatures due to climate change can cause these symbiotic algae to be expelled from the coral, an event known as bleaching, which often leads to death.

Scientists from University of Miami placed corals in tanks and subjected them to increased water temperatures to gain insights into how they may react to global warming by replicating ocean conditions that would lead to both mild and severe coral bleaching.

The central African country of Gabon is providing an invaluable nesting ground for a vulnerable species of sea turtle. During a survey of nearly 600 km of Gabon's coastline, scientists from the University of Exeter uncovered the Atlantic’s largest breeding colony of olive ridley turtles. Study results estimate that there could be up to 9,800 turtle nests per year, compared with around 3,300 in French Guiana and 3,000 in Brazil.

The smalltooth sawfish is the first documented examples of viable parthenogens living in a normally sexually reproducing wild vertebrate.

The researchers analysed telltale markers called microsatellites in 190 sawfish that reveal how related their parents are. In seven fish, the markers suggested their parents were identical to them. The analysis revealed that the seven fish came from three different mothers.

Although seagrass meadows occupy less than 0.2 percent of the world's oceans, they are responsible for more than 10 percent of all carbon buried annually in the sea, according to a research paper published this week in the journal Nature Geoscience.

The paper, "Seagrass Ecosystems as a Globally Significant Carbon Stock," is the first global analysis of carbon stored in seagrasses.

According to Gibraltar’s department of the environment, an artificial reef protested by Spain is now “exploding with life”. Initiated two years ago, the 70 concrete blocks sunk near Gibraltar airport’s runway are already home to a large range of marine species from octopuses to triggerfish.

HMS Tamar was a 4,600 tons displacement sail and steam-powered Royal Navy troopship launched in Britain in 1863. She served as a supply ship from 1897 to 1941 and gave her name to the shore station HMS Tamar in Hong Kong (1897 to 1997).

In 1897 Tamar was hulked as a base ship and used as the Hong Kong receiving ship and served as the 'name' ship for R.N. headquarters until it was replaced by the shore station, which was named HMS Tamar, after the ship.

The shark travelled from the chilly waters off Nova Scotia to the warm, inviting ocean near Venezuela to the clear waters of Puerto Rico and then north again to the waters where he was first caught.

Finland’s accomplished diver and wreck researcher Rauno Koivusaari, who discovered the famous treasure ship Vrouw Maria in 1999, has now also found the wreck of the Hanneke Wrome just south of the island of Jussarö in Finland. According to historic documents, the ship was carrying 10,000 gold coins, estimated to be worth around €50 million today.

The Public Employees for Environmental Responsibility (PEER) has filed a Notice of Intent to Sue the U.S. Fish & Wildlife Service to end the popular swim-with programs by disallowing people to swim within 10 feet of the manatees. In addition, it recommends the expansion of no-human access areas and to designate the entire Kings Bay, Three Sisters Springs and Homosassa Springs as critical manatee habitats.

These proposals do not sit well with some people.
