Tumon Bay is a bay in the United States territory of Guam, opening to the Philippine Sea. It is bounded to the north by Two Lovers Point and to the south by Ypao Point. The entirety of the bay falls within the Tumon Bay Marine Preserve, also known as the Tumon Bay Marine Preserve Area (MPA) and Tumon Preserve, one of five marine preserves on Guam. The Preserve measures 4.54 square kilometers and is roughly two miles long. The platform of the fringing reef that separates the open ocean from the lagoon is up to 1,450 feet (440 m) wide. [1] and up to one mile from the shore. [2] The bay is located off of the Tumon area, the tourist center of the island, in the village of Tamuning. The bay is extensively utilized for recreation and fishing.

Tumon Bay or Agana Bay are the most likely locations that Ferdinand Magellan dropped anchor on March 6, 1521, which was the island's first encounter with Europeans. [3] The bodies of Diego Luis de San Vitores and Pedro Calungsod were thrown into the bay following their murders on April 2, 1672, during the Spanish-Chamorro Wars. [4] In response, the Spanish launched a punitive attack on Tumon, burning several houses and sakman . However, the Spanish column was attacked on both flanks as it waded through the waters of Tumon Bay, losing three soldiers to poison spears. Two Chamorro warriors were killed in the battle. [5] : 30–31  During the Japanese invasion in 1941, the South Seas Detachment under the command of Major-General Tomitarō Horii made landings at Tumon Bay. [6]

In the 1960s, the Government of Guam blasted a shallow cut in the fringing reef opposite San Vitores Beach to allow entry by small boats. As hotels were built along the shore in the 1970s and 1980s, holes to allow swimming at low tide were dredged along the beach at Hilton Hotel, Ypao Beach Park, the Pacific Star (now Marriot) Hotel, and San Vitores Beach. [7]

In 1986 the Guam Division of Aquatic and Wildlife Resources determined that fish stocks had declined 70% in the previous 15 years and began the process of setting aside areas around Guam with limited take. [1] In 1996, Guam passed a law prohibited motorized watercraft from being used inside the Tumon reef, with the exception of jet skis transiting from San Vitores Beach directly through the cut into the open ocean. [8] A dinner boat is also allowed to use the cut to gain entry to the ocean. Fishing boats, even if not motorized, were banned from the lagoon in 1999 when the marine preserve area was established. Currently, only small recreational and paddling craft are allowed to utilize the lagoon. [7] In the 1990s, as hotels filled up the beachfront property along Tumon Bay, the bay was dredged by the hotel community to remove the seaweed that frequently washed ashore and "despoiled the beauty" of the beach.[ citation needed ]

Marine preserves began to be fully enforced in 2001. [9] In 2005, the interagency Guam Coral Reef Monitoring Group began monitoring Tumon Bay. [10] The Tumon Bay preserve comprises 9.2% of all marine protected area on Guam. In a 2009 study, 18% of the preserve was coral, 10% was seaweed, and 1% was seagrasses. [1] Within the Tumon preserve, all species of fish may be caught by hook-and-line. Juvenile (4 inches or less) Goatfish and Jack may additionally be caught from the shore with cast net. Rabbitfish and Convict Tang may be caught from the shore or reef line with cast net. Bottom fishing is allowed from the 100 foot contour outwards. Trolling is allowed from the reef margin seaward for pelagic fish only. [11] Arrests for illegal fishing in Tumon continue to be made. [12] The Guam Long-Term Coral Reef Monitoring Program began partial monitoring of Tumon Bay Marine Preserve in June 2009 and began full data monitoring in 2010. It was determined that the southern and northern halves of the study site had very different benthic communities and the site was redrawn to get adequate monitoring of both communities. [13] A 2010 study found that the establishment of Guam's marine preserves had doubled the death rate by drowning of Chamorro fisherman, with the hypothesis being that they were pushed into more hazardous areas. [14]

It will take many years for the seaweed and fish to come back to their previous levels. The beach along Hotel Row was also covered with rocks, many of which were removed as well.[ citation needed ] The coral reef fringing Tumon Bay suffers from nutrient infusion and algal blooms associated with fresh water seepage from hotels along the beach. The fresh water is likely coming from irrigation systems used by the hotels to maintain tropical garden landscaping around the hotel. The freshwater can be seen leaching into the bay at low tide. Further evidence is the very visible algal blooms created by the nutrient rich fresh water.[ citation needed ]

The bay is continuously utilized for fishing and recreational uses, including swimming and use of small unmotorized watercraft. The lagoon offers sites for both beginner and advanced snorkeling. [15] Outrigger canoe teams sail on the bay out of Matapang Beach. Matapang Beach and Tumon Bay hosted outrigger canoeing at the 1999 South Pacific Games. [16] Scuba diving off of Gun Beach, located on the northern end of the bay, offers what Stars and Stripes states is "often referred to as 'the best shore dive on Guam'". [17] [18]

The San Vitores Beach Japanese Fortification are the remains of World War II-era defensive positions facing the beach of Tumon Bay on the west side of the island of Guam. Located near the stairs to the beach of the Guam Reef Hotel are the remains of two concrete pillboxes built by Japanese defenders during the occupation period 1941–44. One structure, of which little more than a gun embrasure is discernible, is located in the limestone cliff about 10 metres (33 ft) inland from the high tide line, and a second is located about 10 meters south and 8 meters further inland, with only a section of roof slab and supporting columns recognizable.

The Spanish–Chamorro Wars, also known as the Chamorro Wars and the Spanish–Chamorro War, refer to the late seventeenth century unrest among the Chamorros of the Mariana Islands in the western Pacific Ocean against the colonial effort of Habsburg Spain. Anger at proselytizing by the first permanent mission to Guam, which was led by Diego Luis de San Vitores, and a series of cultural misunderstandings led to increasing unrest on Guam and a Chamorro siege of the Hagåtña presidio incited by maga'låhi (Chief) Hurao in 1670. Maga'låhi Matå'pang killed San Vitores in 1672, resulting in a campaign of Spanish reprisal burnings of villages through 1676. Local anger at the attacks against villages resulted in another open rebellion led by Agualin and a second siege of Hagåtña. Governor Juan Antonio de Salas conducted a counter-insurgency campaign that successfully created a system of collaboration in which Guamanians turned in rebels and murderers and transferred most of the people from about 180 villages to seven towns, a policy known as reducción. By the early 1680s, Guam was largely "reduced," or pacified.

<span class="mw-page-title-main">Coral reefs of Tuvalu</span> List of coral reefs in Tuvalu

The coral reefs of Tuvalu consist of three reef islands and six atolls, containing approximately 710 km2 (270 sq mi) of reef platforms. The islands of the Tuvalu archipelago are spread out between the latitude of 5° to 10° south and longitude of 176° to 180°, west of the International Date Line. The islands of Tuvalu are volcanic in origin. On the atolls, an annular reef rim surrounds the lagoon, and may include natural reef channels. The reef islands have a different structure to the atolls, and are described as reef platforms as they are smaller tabular reef platforms that do not have a salt-water lagoon, although they may have a completely closed rim of dry land, with the remnants of a lagoon that has no direct connection to the open sea or that may be drying up.

Underwater diving encompasses a variety of economically and culturally significant forms of diving on the U.S. island territory of Guam. Scuba diving tourism is a significant component of the island's tourist activity, in particular for visitors from Japan and South Korea. Recreational diving by Guam residents has a lesser but still substantial economic impact. Marine biologists have raised concerns about the effect of diving upon the health of some of Guam's reefs. Recreational dive sites on Guam include submerged shipwrecks, such as the double wrecks of SMS Cormoran and Tokai Maru, and natural features, such as Blue Hole.

The largest pit houses the commercial Fish Eye Marine Park tourist attraction, which includes a wooden pier to a underwater observatory and a Seawalker tour of the lagoon bottom. It is visited by more than 200,000 people annually. The Piti preserve is the most ecologically diverse of Guam's five marine preserves. The pit around Fish Eye is a popular snorkeling and recreational diving site.

<span class="mw-page-title-main">Pago Bay</span>

Pago Bay is the largest bay on the U.S. territory of Guam, located at the mouth of Pago River on the island's eastern coast. There is extensive evidence of CHamoru settlement before Spanish colonization during the late seventeenth century. During the Spanish-Chamorro Wars, the Spanish transferred the populations of Tinian and Aguigan to the village of Pago. However, a smallpox epidemic in 1856 killed much of the village's population and the Spanish moved survivors to other villages, leaving the bay shoreline largely uninhabited. The bay is popular with fishermen and recreationalists, and was the site of new housing development in the 2000s.
