The discolouration, foul-smell and dead fish in Sungai Melaka are not caused by pollution, but believed to be due to the ocean current
, said state Housing, Local Government, Environment and Green Technology Committee chairman Datuk Tey Kok Kiew.
These extremely fine admixtures can even reveal the paths an ocean current
has taken in the past information that plays an important role in climate studies.
Gathering information on the Antarctic Circumpolar Current, the largest ocean current
in the world, the instrument was due to spend two years collecting data at a depth of 1,100 metres, before being recovered on Christmas Day in 2013 by a research expedition on the Royal Research Ship James Clark Ross.
However, whereas temperatures in Greenland responded quickly to the ocean current
shutdown and subsequent reboot 1,000 years later, it took hundreds of years for rainfall in the Philippines to be affected and to recover.
Such questions can be approximately addressed with the simpler empirical rule-of-thumb that icebergs drift at the ocean current
velocity plus 2% of the wind velocity.
IHI and Toshiba, together with the University of Tokyo and Mitsui Global Strategic Studies Institute, have conducted R&D financed by Nedo's "R&D of Ocean Energy Technology - R&D of Next-Generation Ocean Energy Power Generation (Underwater Floating Type Ocean Current
Turbine System)" programme since fiscal year 2011.
Prior to the design of offshore wind farms, towers such as these are installed to monitor the meteorological data at the planned site, accruing measurements of atmospheric air pressures, wind velocities and directions, tidal wave conditions and ocean current
velocities and directions at various elevations.
The focus of this expedition is to test several varieties of ocean monitoring devices to help researchers more accurately measure ocean currents
. This type of data can help create more precise ocean current
models for use in response to future oil spills or other disasters.
The boat is submerged upside down in murky waters and surrounded by a strong ocean current
Joseph offers this historical and technical guide to ocean current
measurement, of potential interest to oceanographers and marine researchers of various disciplines.
At her current post, Skemp works on testing and evaluating the potential of ocean currents
to create electricity through ocean current
hydrokinetic and ocean thermal energy conversion.
The ball made its lengthy journey across the Pacific on ocean currents
. "An ocean current
is like a river in the ocean," says Dimitris Menemenlis, an oceanographer at NASA's Jet Propulsion Lab in California.
