Sogod Bay
Sogod Bay is a large bay in the southern part of Leyte Island in the Philippines. An extension of the Bohol Sea, the bay is surrounded by the province of Southern Leyte, and the namesake municipality of Sogod is located at the head of the bay. Panaon Island forms part of the eastern side of Sogod Bay, while Sarangani or Limasawa Island is at the mouth of the bay. Ecology The bay is home to a variety of fishes, is therefore a major fishing ground for the nine municipalities surrounding the bay. Mangko (''Euthynnus affinis'') is its major fishery resource. Seasonal influx of Mangko has provided food and livelihood to the people of Sogod and nearby municipalities. A study of Sogod Bay by Silliman University in 1994 mentioned that there are seven finfish species that are pelagic and are harvested when they enter the bay. Recently, there have been reports of whale shark sightings in the bay. The Subangdaku River is a major tributary of Sogod Bay, emptying into the bay at the mun ...

Bohol Sea
The Bohol Sea, also called the Mindanao Sea, is a sea located between the Visayas and Mindanao islands in the Philippines. It lies south of Bohol and Leyte and north of Mindanao. Siquijor and Camiguin are its two major islands. The major cities along the coastline of the sea are Cagayan de Oro, Iligan, Butuan, Dumaguete, Ozamiz and Tagbilaran. The sea connects to the Philippine Sea through the Surigao Strait, to the Camotes Sea both through the Canigao Channel and Cebu Strait, and to the Sulu Sea through the strait between Negros Island and Zamboanga Peninsula. Scuba diving The Bohol Sea is home to a large variety of premier scuba diving locations, dive charter boats, and hotels that cater to divers. Around the area of Tagbilaran and Balicasag Island there are numerous wall dives that range from . Water temperatures are very warm and most divers use a 3/2 short wetsuit to dive the location. Sea life is abundant and includes clownfish, lionfish, barracuda, dolphins, hug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siltation
Siltation, is water pollution caused by particulate terrestrial clastic material, with a particle size dominated by silt or clay. It refers both to the increased concentration of suspended sediments and to the increased accumulation (temporary or permanent) of fine sediments on bottoms where they are undesirable. Siltation is most often caused by soil erosion or sediment spill. It is sometimes referred to by the ambiguous term "sediment pollution", which can also refer to a chemical contamination of sediments accumulated on the bottom, or to pollutants bound to sediment particles. Although "siltation" is not perfectly stringent, since it also includes particle sizes other than silt, it is preferred for its lack of ambiguity. Causes The origin of the increased sediment transport into an area may be erosion on land or activities in the water. In rural areas, the erosion source is typically soil degradation by intensive or inadequate agricultural practices, leading to soil eros ...

Ecology
Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and it is not synonymous with environmentalism. Among other things, ecology is the study of: * The abundance, biomass, and distribution of organisms in the context of the environment * Life processes, antifragility, interactions, and adaptations * The movement of materials and energy through living communities * The successional development of ecosystems * Cooperation, competition, and predation within and between species * Patterns of biodiversity and its effect on ecosystem processes Ecology has practical applications in conservation biology, wetland management, natural resource managemen ...

Quarry
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subangdaku River
The Subangdaku River is the largest river in Southern Leyte, Philippines. It drains into the Sogod Bay at the municipality of Sogod. The river's name means "big river" or "wide river" in Cebuano. For years, following the flooding of the river, it created an issue over the province. It has been quarried and re-channeled which caused the incidents. After many attempts, the issue remained unsolved. Formation By description, it can be considered as a braided river composed of several channels from near areas that divide and again reunite in a certain area forming an alluvial fan with very wide floodplain. As such, the river usually became hazardous during typhoon after a heavy rain. The river has been meandering its natural course. The occurrence is being observed by natives living along the river every time a flood occurs. Environmental issues The ecology of the Subangdaku River has been disturbed by human activity, such as: a) noise such as those caused by grinding of rocks dur ...

"Sizing ocean giants: patterns of intraspecific size variation in marine megafauna". ''PeerJ'' 3:e715 . The whale shark holds many records for size in the animal kingdom, most notably being by far the largest living nonmammalian vertebrate. It is the sole member of the genus ''Rhincodon'' and the only extant member of the family Rhincodontidae, which belongs to the subclass Elasmobranchii in the class Chondrichthyes.

Pelagic
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. Th ...
