Sentences with phrase «measured using tide»

Global mean sea level is measured using tide gauge records and also, since 1993, satellite data.

Sea level changes can be measured using tide gauges and remotely from space using satellite altimeters.

Not exact matches

Where a low - tide elevation is situated wholly or partly at a distance not exceeding the breadth of the territorial sea from the mainland or an island, the low - water line on that elevation may be used as the baseline for measuring the breadth of the territorial sea.

Thanks to Swarm's precise measurements along with those from Champ — a mission that ended in 2010 after measuring Earth's gravity and magnetic fields for more than 10 years — scientists have not only been able to find the magnetic field generated by ocean tides but, remarkably, they have used this new information to image the electrical nature of Earth's upper mantle 250 km below the ocean floor.

As a result, the system used was able to measure deformation, notably caused by Earth tides, at a resolution of one part per billion.

Others have used tide gauge data to measure GMSL acceleration, but scientists have struggled to pull out other important details from tide - gauge data, such as changes in the last couple of decades due to more active ice sheet melt.

When satellites pass over the sky, the GNSS tide gauge uses signals direct from the satellite and signals reflected off the sea surface to measure the sea level.

It uses the satellite data of sea level to determine the typical variability patterns of the sea surface and thus to establish the link between the locally measured tide gauge values and the global sea level.

Further, the use of tide gauges in an attempt to measure global sea levels — however defined — is nearly as pointless as using tree rings to measure temperatures.

«In our study we used sea level data measured by various tide gauges throughout the twentieth century to see how extreme sea level during hurricanes has changed with temperature.»

Tide heights near ice shelves can be measured using traditional coastal tide gauges and bottom pressure recorders, while currents can be measured with meters on moorings in the open ocean or deployed through boreholes drilled through ice shelves, which are the floating portions of ice sheTide heights near ice shelves can be measured using traditional coastal tide gauges and bottom pressure recorders, while currents can be measured with meters on moorings in the open ocean or deployed through boreholes drilled through ice shelves, which are the floating portions of ice shetide gauges and bottom pressure recorders, while currents can be measured with meters on moorings in the open ocean or deployed through boreholes drilled through ice shelves, which are the floating portions of ice sheets.

With new measures to cap coal use and restrict imports of low quality coal in China, it appears the tide is turning against the coal exporters.

Measuring the worlds average temperature to tenths of a degree is like trying to measure the «height» of the sea using a tide gauge in rough weather.

Now I am not a great fan of the aggregated tide gauge record seeing as it relies on so few gauges (as cited) most with short histories (as cited) or have moved (as cited) or have been interpolated (as cited) To globally aggregate such low grade information only compounds the errors However, anyone working on flood defence work would use a tide gauge as it provides a more accurate record of the place where the sea actually hits the land, where people live, as opposed to satellites which measure open sea.

But practical measures ARE ipos facto a good use of money to respond to slightly rising sea levels, but in fact mostly to occasional surges from spring tides, storm surges — WEATHER.

During the time of conducting our study, the reliability of the HADS as a clinical screening tool was critically questioned noting that although the HADS was used in TIDES, different measures were recommended from that international study.36 These measures were the PHQ - 9 for depression and the GAD - 7 for anxiety.4 36 Both these measures are recommended in the international guidelines for mental health screening of patients with CF, 11 which are since being used in CF clinical settings.15 31 Because of the current shift away from using HADS as a screening tool for depression and anxiety in CF, and because of the small sample sizes in each group (online and paper - based), we did not test measurement invariance to determine if the online version of HADS is equivalent to the paper based version.
