Sentences with phrase «calculating mean sea level»
Several countries had already set up coastal tide gauges — essentially, a float attached to a pen that traced a line on a chart — and were calculating mean sea level, defined as the average of sea level measured at regular intervals between high and low tide.

«From now on, continues Castelltort, we know that by calculating the ratio between 13C and 12C sampled in similar slope deposits close to continents, we can have an indication of the sea level, which means it's possible to better predict the distribution of sedimentary rocks in our subsurface.»
«As length scales become smaller from several hundred miles to a few tens of miles, we discovered the point at which geostrophic balance becomes no longer valid — meaning that sea level is no longer useful for calculating ocean circulation,» said Qiu, professor at the UHM School of Ocean and Earth Science and Technology (SOEST).
Scientists use sea level as a means to calculate ocean circulation because satellites circle Earth daily, acquiring sea level data frequently and accurately.
