Sentences with phrase «when seawater temperatures»

The pre-stress conditions are expected to disappear when seawater temperatures rise by as little as 0.5 °C, such as predicted for the near future.

They were able to maintain this strong increase in oxygen uptake even when the seawater temperature was increased to 37 °C — a temperature at which coral reef fish can not even survive for a short time.»

Not exact matches

When the team warmed tanks of seawater, they found phytoplankton grew slightly faster with every degree of temperature rise.

The Calera process essentially mimics marine cement, which is produced by coral when making their shells and reefs, taking the calcium and magnesium in seawater and using it to form carbonates at normal temperatures and pressures.

When seawater freezes it expels its salts, producing a layer of very dense, briny water at the freezing temperature.

«The other carbon dioxide problem», «the evil twin of global warming», or part of a «deadly trio», together with increasing temperatures and loss of oxygen: Many names have been coined to describe the problem of ocean acidification — a change in the ocean chemistry that occurs when carbon dioxide (CO2) from the atmosphere dissolves in seawater.

That may seem small at first, but over time, especially when combined with other sources of sea level rise such as melting Greenland glaciers and the expansion of seawater as ocean temperatures increase, it adds up.

When temperatures began warming up, freshwater from melting ice that flowed into the Nordic Seas would have diluted salty seawater near the surface.

A small rise or fall in temperature seemed likely to cause a rise or fall in the gas levels (for example, when seawater got warmer it would evaporate some CO2 into the atmosphere, whereas it would absorb the gas during a cooling period).

Coral reefs are threatened by rising water temperatures, ocean acidification, and sea - level rise.3, 5 Coral reefs typically live within a specific range of temperature, light, and concentration of carbonate in seawater.6 When increases in ocean temperature or ultraviolet light stress the corals, they lose their colorful algae, leaving only transparent coral tissue covering their white calcium - carbonate skeletons.6 This phenomenon is called coral bleaching.

Corals may bleach — a breakdown of the symbiosis between the reef - building animal and the microalgae in its tissue — when the seawater warms past a threshold (e.g. temperatures are ~ 1 - 2 deg C warmer than the usual annual maximum for a whole month).

In past climate changes, warming temperatures produced increased CO2 concentrations in the atmosphere, unlike today, when humans release CO2 which is partially absorbed by plants and by seawater.
