Some of the most influential factors of the IME include local geomorphology, such as island type and reef slope
gradient, both of which create variations in how 'upwelling' sweeps nutrients from the deep ocean up into the shallows, providing basal energetic resources for higher trophic levels such as corals and reef fish.
Almost without exception, every reef we flew across showed consistently high levels of bleaching, from the reef slope
right up onto the top of the reef.
Three transects were oriented along the reef flat/crest interface at a 0-2 m depth contour, and three transects were oriented along the reef slope
at the 2-5m depth contour.
Habitats of larger foraminifera on the reef slope
of Sesoko Island Okinawa Japan.
It lies on the steep reef slope
, starting at around 10 metres going all the way down to 80 metres.
Several patch reefs exist to the North of the keys while the most important and well developed fringing reefs are found in the Southern side where the most conspicuous are reefs crests (1-3m depth), with large stands of dead Acropora palmata and some interspersed live colonies comprising the main component of three dimmensional structure, and reef slopes
(12-15m the shallow reef slope
and 20-30m the deep reef slope
) with Siderastrea siderea and Agaricia agaricites as dominant species of coral assemblages.
However, she points out that the corals studied lie on the outer reef slope
, that Moorea is not heavily populated, and that the main human impact has been fishing.
coelestis were collected by divers using hand nets and clove oil from two sites on the reef slope
(ocean 1 and 2) and two sites within the lagoon (lagoon 1 and 2) at OTI (23[degrees]30'S, 152[degrees]06'E; n=7 per site).
The dominant macroalgae that live in the deep reef slope
and in the sand plains, are characterized for their great space competitive ability and have been invading the shallow coralline banks (< 13 m), killing corals and other organisms.
Periodic mass-bleaching and elevated sea level temperatures: bleaching of Outer reef slope
communities in Moorea, French Polynesia.
On most sides of Heron and Wistari reefs, the reef slope
consists of large tracts of contiguous coral reef.
Four different ecological zones of Enmedio Reef were identified for the collection and study of the distribution of macroalgae, including the lagoon, reef flat, reef slope
and deep water areas (more than four meters) such as channels, "blue holes" and deep areas adjacent to the reef.
