Environmental Concerns for the Future of Gulf Coral Reefs

The Gulf is located in a subtropical, hyper-arid region. It is shallow, and bordered by several wealthy states (Fig. 16.1) undergoing rapid economic growth involving substantial construction along shores and offshore regions, underpinned by its oil and gas industry, and by wealth derived from financial centres. Thriving economic activity has, over the past few decades, begun to exert significant pressure on the Gulf’s marine environment. It is changing rapidly, by developments which include construction, substantial coastline alterations, habitat loss, creation of beds of shifting or suspended sediments, and temperature and salinity changes in restricted water flows along the coast, as well as by climate warming. The Gulf suffers from a “shifting baseline syndrome” (Pauly 1995; Sheppard 1995) and it is difficult to find any meaningful baselines, not only because of ongoing, intensive constructions that cause large-scale alterations of the environment, but also because of several recent episodes of marine mortality from seawater warming.
