A key aspect of the work being done during the GRE involves the characterization of the diversity (number of different species) of different organisms – fish, corals, other invertebrates and algae. While species inventories for algae have been completed here,
Several hours after dark on Halloween, a large school of bait fish attracted to the lights given off by the Golden Shadow, congregated near the aft deck to feed on plankton. This fish behavior (and the lights) also attracted other
The average person doesn’t get too excited about algae, which most know as seaweed. It smells when it accumulates on the beach and rots, it can outcompete coral when left unchecked, and it’s generally considered bad for reefs, especially when
Two days of diving and our coral reef research is well underway in Isle de Pins, New Caledonia. Although sea conditions were very murky, we explored three lagoonal patch reefs yesterday and successfully completed our standardized coral, benthic and fish
Our 17th mission of the Global Reef Expedition is to New Caledonia, a special collectivity (a former territory under special status) of France located in the southwest Pacific about 1200 km from Australia, and home to some of the most
One of the most colorful and diverse groups of invertebrates found on coral reefs are soft corals (known scientifically as Alcyonaceans). These cnidarians are related to stony (scleractinian) corals, but they lack a massive, calcified skeleton and have eight hollow
On our second day of diving we had our first encounter with a sea snake. While most of the 62 described species are true aquatic snakes, we observed one of the more primitive snakes, banded sea kraits, Laticauda colubrina. This
The Kingdom of Tonga contains some of the most unique and extensive coral reef environments found in the central south Pacific, with over 1500 square kilometers of reef area. These Tonga coral reefs are located due east of the 35,000
One of the most unusual group of animals found on the reef are the echinoderms. So named because of their “spiny skin”, these animals are pentamerous or radially symmetrical (five point). Found only in the sea, they include sea urchins,
Reef building corals start out from a small larvae (planula) that settles onto the reef, or from a fragment that has broken off another colony. The polyps that make up the coral divide, repeatedly, into two or more daughter polyps,
