Sentences with phrase «sea level measurements»

I think sea level measurements are unreliable at best due to the fact that the measuring stations are not vertically static.
If you write that «Latest sea level measurements from benchmark island shows sea level is dropping», you need to be told, if you are still there, that that is rubbish.
But concerning the ocean heat uptake, have you some confidence in altimetric sea level measurement?
Summary Short records of sea level measurements by the Ordnance Survey at 31 locations in 1859 — 1860, together with recent Mean Sea Level (MSL) information from the UK tide gauge network, have been used to estimate the average rates of sea level change around the coast of Great Britain since the mid-19th century.
Sea level measurements by satellite, have been a mishmash of data not unlike OHC prior to ~ 2004 (XBT biases, data splicing etc.).
Described in a research paper published in the journal «Geophysical Research Letters», the «smoke rings» were discovered by analysing sea level measurements taken from satellites together with sea surface temperature images from the same time and place.
«Virtual contact lenses for radar satellites: Algorithm improves sea level measurements
The scientists have also shown that existing coastal GNSS stations, installed primarily for the purpose of measuring land movements, can be used to make sea level measurements.
Vertical land movements such as resulting from glacial isostatic adjustment (GIA), tectonics, subsidence and sedimentation influence local sea level measurements but do not alter ocean water volume; nonetheless, they affect global mean sea level through their alteration of the shape and hence the volume of the ocean basins containing the water.
But a look at natural ocean variation shows that official sea level measurements are nonsense.
It should also be noted that global average sea level measurements show increases of 1.1 Millimeter per year.
«In summing up these and other of their several findings, Parker and Ollier write that «the evidences from real sea level measurements do not support the IPCC models or the even more alarming predictions [made by the National Research Council and California Ocean Science Trust].
Over the past few decades, sea level measurements taken using satellites show that this trend has continued, with the current rate of increase standing at about 3.36 mm per year.
Raw data collected from altimeters have been re-processed and collated with wind speed data from scatterometers and sea level measurements from tide gauges, to show the spatial structure of each storm.
Regardless of that point, sea level measurement and analysis is highly complex and problematic.
So, in order to convert a particular «satellite - sea surface distance» into a sea level measurement, the «satellite - Earth's surface distance» also needs to be independently measured, e.g., using the DORIS system.
Sea level measurements have been made for over 100 years in some places, but the network of tide gauges with long records provides only limited global coverage.
