Sentences with phrase «seasonal ocean currents»

In order to get to those nursery habitats, the larvae have to be carried by seasonal ocean currents.

Not exact matches

Seasonal weather fluctuations also depend on factors such as proximity to oceans or other large bodies of water, currents in those oceans, El Nino / ENSO and other oceanic cycles, and prevailing winds.

An initial high - resolution study shows that off Peru the ocean layer called «oxygen minimum» where life is limited is sensitive to the intensity of the seasonal current from the equator that brings water containing little oxygen to the coastal ecosystem.

The team, which includes Professor Baldwin, will lead innovative new research, which aims to advance current understanding of three key conditions that influence seasonal weather across the continent — the North Atlantic upper - ocean heat content, Arctic sea - ice, and the stratosphere.

Newly hatched leatherback sea turtles born on beaches in Costa Rica ride the ocean's Route 66, zipping away from shore — and away from predators — on fast and seasonal currents, a new study suggests.

Beach Movement A natural phenomenon on North Island, the beaches migrate around the island in a ceaseless seasonal pattern dictated by the ocean currents.

Such as wildfire feedback, coastal erosion, weather / atmospheric anomalies, seasonal changes, species adaptation, ocean currents etc..

Using an ocean circulation model for the shelf, the authors find that surface temperatures may increase by 0.5 to 2.0 °C, seasonal surface salinity may drop by up to 2 PSS in some areas, and that Haida Eddies will strengthen, as will the Vancouver Island Coastal Current and freshwater discharges into coastal waters.

Further, just as seasonal - to - interannual predictions start from an estimate of the state of the climate system, there is a growing realization that decadal and longer - term climate predictions could be initialized with estimates of the current observed state of the atmosphere, oceans, cryosphere, and land surface.

Climate models are like weather models for the atmosphere and land, except they have to additionally predict the ocean currents, sea - ice changes, include seasonal vegetation effects, possibly even predict vegetation changes, include aerosols and possibly atmospheric chemistry, so they are not like weather models after all, except for the atmospheric dynamics, land surface, and cloud / precipitation component.

This study shows that a weaker surface ocean current system produces colder coastal SST's along the Atlantic coast of Florida, thereby reducing the length and the total seasonal accumulation of rainfall in the wet season of Peninsular Florida relative to the simulation in which these currents are stronger.

The length of the growing season in interior Alaska has increased 45 % over the last century7 and that trend is projected to continue.8 This could improve conditions for agriculture where moisture is adequate, but will reduce water storage and increase the risks of more extensive wildfire and insect outbreaks across much of Alaska.9, 10 Changes in dates of snowmelt and freeze - up would influence seasonal migration of birds and other animals, increase the likelihood and rate of northerly range expansion of native and non-native species, alter the habitats of both ecologically important and endangered species, and affect ocean currents.11

For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.134

One of Phil's most successful uses of ship drift data was to study seasonal variability in the equatorial currents in the Atlantic Ocean.

How the seasonal weather changes at a particular climate depends on ocean currents so you can have correlation between volcanic eruptions and «global climate» but one is not necessarily affected by the other.
