Sentences with phrase «variable ocean conditions»

In the model, populations experience different within - population environmental conditions and the same time - variable ocean conditions, the response to which can depend on a quantitative genetic trait.

Not exact matches

Ocean conditions are highly variable and sometimes dangerous.

Weather Conditions in the Santa Barbara Channel and around the islands are variable and the ocean is unforgiving.

The conditions also bolster the views of ice and climate specialists who have stressed that the many factors shaping Arctic conditions year by year, from winds and atmospheric pressure to highly variable ocean currents and soot, still dominate the influence of heat trapped by building greenhouse gases.

They stressed this was a rough projection and did not account for a vast range of variables in ocean conditions to come.

Ice retreat depends strongly on the amount of solar heating of the surface ice and ocean; clear sky conditions early in the melt season can go a long ways towards helping ice retreat later in the season, so this is one of the variables that will be monitored closely (e.g., in the Barrow coastal sea ice break - up forecast, see below).

Whereas at the three sites from the central Arctic Ocean an extended to perennial sea ice cover was probably predominant, sea ice conditions were much more variable along the northern Barents Sea continental margin as reflected in the data of Core PS2138 - 2 (Fig. 2d).

Observations suggest that variability in oceanographic conditions in the Arctic is very largely driven by the consequences of the flows through open passages to both Atlantic and Pacific Oceans, which themselves respond to the different and characteristic variability of the circulation patterns of each ocean: each inflow is not only variable in volume of water transported but also in the temperature of the water imported.

The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch Cycles.

Another recent study, by scientists from the U.K., Hawaii and Massachusetts, concluded that «marine and freshwater assemblages have always experienced variable pH conditions,» and that «in many freshwater lakes, pH changes that are orders of magnitude greater than those projected for the 22nd - century oceans can occur over periods of hours.

An important implication of these findings is that processes that strengthen the impact of one ocean variable on another may cause more frequent adverse climate conditions.
