Park waters lie within the Florida Keys National Marine Sanctuary, established in 1990. Today, the venerable sanctuary comprises 2,900 square nautical miles of coastal waters from northernmost Key Largo south to the Dry Tortugas. Sanctuary Preservation Areas established as protected no-take zones enable fish and crustacean populations to thrive and grow.

  • Into the Deep: Scuba-Diving Faithful Honor Christ Underwater
    Into the deep: Scuba-diving faithful honor Christ underwater VATICAN CITY (CNS) — Imagine a pilgrimage where the faithful gear up with scuba fins and oxygen tanks or snorkel sets rather than hiking boots, sun hats and trek poles. That’s what happens in the crystal-clear waters of the Paradise Gulf along the Italian Riviera near Genoa. Pilgrimages to the bronze statue of Christ of the Abyss, an 8- foot-tall sculpture submerged 56 feet below the surface of the sea, were featured in the Vatican newspaper, L’Osservatore Romano, July 28. The statue, located offshore halfway between the small coastal villages of Camogli and Portofino, was the first known statue of Christ to be placed in the sea as a sign of his peace and protection for those who live, work or play by the water, to be a place of prayer and to commemorate those who have died there. According to Italian news, sports and tourism websites, the idea came from Genoa-born Duilio Marcante, the so-called “father” of underwater diving education. The statue’s home would be near where Marcante’s friend, Dario Gonzatti, died during a dive in 1950. Gonzatti, Marcante and Egidio Cressi created and tested the first prototypes of “Self-Contained Oxygen Breathing Apparatus” (ARO) in those waters. In 1952, Marcante proposed the idea of creating an underwater “Christ of the Abyss” to Giacomino Costa, a Genovese entrepreneur, shipowner and then-president of the Catholic Italian Sports Center. Costa asked Cardinal Giuseppe Siri of Genoa whether it would be inappropriate to place a religious statue on the bottom of the sea.

This 'rise of slime,' as one scientist calls it, is killing larger species and sickening people. By Kenneth R. Weiss Times Staff Writer July 30, 2006 MORETON BAY, AUSTRALIA — The fireweed began each spring as tufts of hairy growth and spread across the seafloor fast enough to cover a football field in an hour. When fishermen touched it, their skin broke out in searing welts. Their lips blistered and peeled. Their eyes burned and swelled shut. Water that splashed from their nets spread the inflammation to their legs and torsos. "It comes up like little boils," said Randolph Van Dyk, a fisherman whose powerful legs are pocked with scars. "At nighttime, you can feel them burning. I tried everything to get rid of them. Nothing worked." As the weed blanketed miles of the bay over the last decade, it stained fishing nets a dark purple and left them coated with a powdery residue. When fishermen tried to shake it off the webbing, their throats constricted and they gasped for air. After one man bit a fishing line in two, his mouth and tongue swelled so badly that he couldn't eat solid food for a week. Others made an even more painful mistake, neglecting to wash the residue from their hands before relieving themselves over the sides of their boats.

For further information contact the UOW Library: [email protected] Mangroves and coral reefs: David Stoddart and the Cambridge physiographic tradition Abstract Mangroves are particularly extensive on sheltered, macrotidal, muddy tropical coastlines, but also occur in association with coral reefs. Reefs attenuate wave energy, in some locations enabling the accretion of fine calcareous sediments which in turn favour establishment of seagrasses and mangroves. Knowledge of the distribution and ecology of both reefs and mangroves increased in the first half of the 20th century. J Alfred Steers participated in the Great Barrier Reef Expedition in 1928, and developed an interest in the geomorphological processes by which islands had formed in this setting. It became clear that many mangrove forests showed a zonation of species and some researchers inferred successional changes, even implying that reefs might transition through a mangrove stage, ultimately forming land. Valentine Chapman studied the ecology of mangroves, and Steers and Chapman described West Indian mangrove islands in the 1940s during the University of Cambridge expedition to Jamaica. These studies provided the background for David Stoddart's participation in the Cambridge Expedition to British Honduras and his PhD examination of three Caribbean atolls.

  • Mollusks Background the Florida Keys Marine Ecosystem Supports a Diverse Fauna of Mollusks Belonging to Several Orders
    2010 Quick Look Report: Miller et al. VII. Abundance and Size of Selected Mollusks Background The Florida Keys marine ecosystem supports a diverse fauna of mollusks belonging to several orders. Opisthobranch mollusks, for example, are represented by at least 30 species of sea slugs (Sacoglossa) and 23 species of nudibranchs (Nudibranchia) (Clark and DeFreese 1987; Levy et al. 1996), including at least three endemic species (Clark 1994). Data on the status and trends of mollusk populations and habitat utilization patterns in the Florida Keys, with the exception of queen conch (Strombus gigas), are generally limited (Marcus 1960; Jensen and Clark 1983; Clark and DeFreese 1987), as most previous studies have been qualitative in nature (Clark 1994; Trowbridge 2002). Clark (1994) noted a declining population trend for the lettuce sea slug, Elysia (Tridachia) crispata Mörch (see cladistic analyses in Gosliner 1995; Jensen 1996) in southern Florida, based upon qualitative comparisons of occurrence and population densities between 1969-80 and 1987-93. About 50% of the nearshore populations assessed by Clark (1994) nearly 17 years ago were declining due to habitat destruction, siltation, eutrophication, and over- collection, particularly evident in nearshore habitats. Since 2001, we have conducted intermittent surveys of various gastropod mollusk species in conjunction with assessments of other benthic variables. For example, we encountered unusually high densities of lettuce sea slugs among 63 shallow fore reef sites during June-September 2001. While sacoglossans are not particularly rare in many shallow-water marine habitats where densities correlate with algal biomass (Clarke and DeFreese 1987), our observations offshore were considered unusual because fleshy algal cover tends to be relatively low (Chiappone et al.

  • III. Species Richness and Benthic Cover
    2009 Quick Look Report: Miller et al. III. Species Richness and Benthic Cover Background The most species-rich marine communities probably occur on coral reefs and this pattern is at least partly due to the diversity of available habitats and the degree to which species are ecologically restricted to particular niches. Coral reefs in the Indo-Pacific and Caribbean in particular are usually thought to hold the greatest diversity of marine life at several levels of biological diversity. Diversity on coral reefs is strongly influenced by environmental conditions and geographic location, and variations in diversity can be correlated with differences in reef structure. For example, shallow and mid-depth fore-reef habitats in the Caribbean were historically dominated by largely mono-specific zones of just two Acropora species, while the Indo-Pacific has a much greater number of coral species and growth forms. Coral reefs are in a state of decline worldwide from multiple stressors, including physical impacts to habitat, changes in water quality, overfishing, disease outbreaks, and climate change. Coral reefs in a degraded state are often characterized by one or more signs, including low abundances of top-level predators, herbivores, and reef-building corals, but higher abundances of non-hermatypic organisms such as seaweeds. For the Florida Keys, there is little doubt that areas historically dominated by Acropora corals, particularly the shallow (< 6 m) and deeper (8-15 m) fore reef, have changed substantially, largely due to Caribbean-wide disease events and bleaching. However, debate continues regarding other causes of coral reef decline, thus often making it difficult for resource managers to determine which courses of action to take to minimize localized threats in lieu of larger-scale factors such as climate change.
