Sentences with phrase «detect changes in mass»

This spring, NASA and the German Research Centre for Geosciences are scheduled to launch the Gravity Recovery and Climate Experiment Follow - On (GRACE - FO) mission, twin satellites that will continue the original GRACE mission's legacy of tracking fluctuations in Earth's gravity field in order to detect changes in mass, including the mass of ice sheets and aquifers.

Not exact matches

[1] The ripples in spacetime known as gravitational waves are created by moving masses, but only the most intense waves, created by rapid speed changes of very massive objects, can be detected by the current generation of detectors.

Remarkably, they found that the decrease in the mass of ice during this period was mirrored in GOCE's measurements, even though the mission was not designed to detect changes over time.

Then they used the PNNL - developed accurate mass and time (AMT) tag proteomic approach to detect the changes in the abundance of STM proteins.

The completion of a draft genome sequence for the microorganism Methanosarcina barkeri has enabled use of high - throughput technologies such as microarrays and mass spectrometry of proteins to detect global changes that occur in response to experimental treatments.

Bioelectrical impedance vector analysis (BIVA) expresses tissue hydration status and body cell mass solely while considering the impedance vector relative to a population of healthy individuals (24); this was a valid method for detecting changes in hydration (classified as under -, normal or overhydration) and body fluid volume changes (25).

Changes in ocean color — a measure of phytoplankton mass — detected from space allowed researchers to calculate their photosynthetic rates and correlate these changes to the cChanges in ocean color — a measure of phytoplankton mass — detected from space allowed researchers to calculate their photosynthetic rates and correlate these changes to the cchanges to the climate.

However, detecting acceleration is difficult because of (i) interannual variability in GMSL largely driven by changes in terrestrial water storage (TWS)(7 ⇓ — 9), (ii) decadal variability in TWS (10), thermosteric sea level, and ice sheet mass loss (11) that might masquerade as a long - term acceleration over a 25 - y record, (iii) episodic variability driven by large volcanic eruptions (12), and (iv) errors in the altimeter data, in particular, potential drifts in the instruments over time (13).
