The ocean currents surrounding the Philippines: (1) Mindanao Current, (2) Mindanao Undercurrent (dotted to indicate that it is deeper than the other currents shown), (3) Mindanao Eddy, (4) North Equatorial Current, (5) Kuroshio current, (6) the beginnings and feeder currents of the Kuroshio (gradated to indicate that it strengthens to the North), (7) Indonesian Throughflow, and (8) North ...
The Philippines' National Mapping and Resource Information Authority (Filipino: Pambansang Pangasiwaan sa Pagmamapa at Dulugang Kaalaman), abbreviated as NAMRIA, is an agency of the Philippine government under the Department of Environment and Natural Resources responsible for providing the public with mapmaking services and acting as the central mapping agency, depository, and distribution ...
The Mediterranean Sea had two high tides and low tides, though Galileo argued that this was a product of secondary effects and that his theory would hold in the Atlantic. However, Galileo's contemporaries noted that the Atlantic also had two high tides and low tides per day, which led to Galileo omitting this claim from his 1632 Dialogue. [27]
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Filipino: Pangasiwaan ng Pilipinas sa Serbisyong Atmosperiko, Heopisiko at Astronomiko, [4] abbreviated as PAGASA, which means "hope" as in the Tagalog word pag-asa) is the National Meteorological and Hydrological Services (NMHS) agency of the Philippines mandated to provide protection against natural calamities ...
The water stops rising, reaching a local maximum called high tide. Sea level falls over several hours, revealing the intertidal zone; ebb tide. Oscillating currents produced by tides are known as tidal streams or tidal currents. The moment that the tidal current ceases is called slack water or slack tide. The tide then reverses direction and is ...
Tide tables forecast the time of the next high water. [6] [7] The difference between these two times is the lunitidal interval. This value can be used to calibrate tide clock and wristwatches to allow for simple but crude tidal predictions. Unfortunately, the lunitidal intervals vary day-by-day even at a given location.

The tides, the Coriolis effect, changes in direction and strength of wind, salinity, and temperature are the main factors determining ocean currents. The thermohaline circulation (THC) ( thermo- referring to temperature and -haline referring to salt content ) connects the ocean basins and is primarily dependent on the density of sea water .
