The reef is named after HMS Looe, which ran aground on the reef and sank in 1744. In August 1994, RV Columbus Iselin , a research vessel owned by the University of Miami , ran aground on Looe Key and damaged approximately 164 m 2 (1,770 sq ft) of living coral and a larger area of reef framework.

Nav finder and underwater compass – basic underwater navigation tools Suunto SK-7 diving compass in aftermarket wrist mount with bungee straps. Diver navigation, termed "underwater navigation" by scuba divers, [1] is a set of techniques—including observing natural features, the use of a compass, and surface observations—that divers use to navigate underwater.
The Sirena Deep, originally named the HMRG Deep, was discovered in 1997 [1] [2] by a team of scientists from Hawaii. [2] Its directly measured depth of 10,714 m (35,151 ft) is third only to the Challenger Deep and Horizon Deep , currently the deepest known directly measured places in the ocean.
The reef's rocky sandstone outcrops, submerged beneath 60 to 70 feet (18 to 21 m) of water, can be as tall as 2 to 3 metres (6 ft 7 in to 9 ft 10 in) and are highly complex. [2] These nooks and crannies provide plenty of places for marine invertebrates to latch on to and for fish to hide in. Together these animals form a dense tapestry of ...
The reef is quite large compared to its neighbours, stretching 40 kilometres (25 mi) north to south. A continuous 15 kilometres (9 mi) reef barrier stretches down the Eastern edge. [5]: 2206 Rising up from water over 1 kilometre (1 mi) deep, most of the reef lies at a depth of just 1–4 metres (3–13 ft).
DSSV Pressure Drop and DSV Limiting Factor at its stern. In February 2019, however, the Five Deeps Expedition, led by its survey ship DSSV Pressure Drop, has recommended that the location of the Meteor Deep be "relocated" to the newly discovered, truly deepest location at and 8,266 metres (27,119 ft) ± 13 metres (43 ft) in depth, given the precision of the new survey
Cod Hole is one of the best known dive sites in the world and is located on the northern end of the Great Barrier Reef in Queensland, Australia on ribbon reef number 10. [1] It is notable for and is named after the dozen or so potato cod that live there. The sanctioned feeding of these fish and number of visitors to the site has also made it a ...
