Sentences with phrase «pelagic ecosystems»
The phrase "pelagic ecosystems" refers to the habitats and living organisms that exist in the open ocean, away from the coast or the seafloor. It includes both the surface waters and the deeper layers of the ocean. Pelagic ecosystems support a wide range of marine life, including fish, plankton, whales, and many other species.

In a long - term field study led by GEOMAR Helmholtz Centre for Ocean Research Kiel, an international team of scientists investigates the effects of ocean acidification on pelagic ecosystems in the subtropical Atlantic.

Quoting the abstract for our readers: It is currently unclear whether observed pelagic ecosystem responses to ocean warming, such as a mid-1970s change in the eastern North Pacific, depart from typical ocean variability.
It is currently unclear whether observed pelagic ecosystem responses to ocean warming, such as a mid-1970s change in the eastern North Pacific, depart from typical ocean variability.
A long - lived paradigm in polar oceanography is that arctic pelagic ecosystems, characterized by short food webs, remain in a dormant state throughout most of the winter season beneath the sea - ice cover, which can last 8 — 10 months in some regions.
Unlike pelagic ecosystems, coastal ecosystems are often dominated by benthic ecosystems, including engineering species (e.g. corals, seagrass, macroalgae, salt marshes, mangroves, sponges, oyster reefs) with the capacity to modulate the chemical and physical conditions of their environment (Gutiérrez et al. 2011).
In the end, they collected the most comprehensive long - term data set on the effects of ocean acidification on pelagic ecosystems.
For the first time, an international team of 70 marine scientists investigates impacts of ocean acidification on pelagic ecosystems.
Other than telling us that coral reefs (and Pelagic ecosystems) are in trouble — I have already kissed the coral reefs goodbye due to temperature increases alone — no firm conclusions were drawn about ocean acidification and its affects on ocean biology.
Overexploitation of living resources, such as krill, fish, and their associated bycatch, is a major threat to the pelagic ecosystem.
Given the lack of detailed proxy records to trace simultaneously biochemical baselines and length of food webs, assessing the extent to which biogeochemical cycling and community structure in pelagic ecosystems have changed over the past century is difficult, as is attributing change to natural cycles versus anthropogenic disturbances.
While there is little doubt that dissolved oxygen concentrations exerted a key control on benthic ecosystems during the past, as they do today, the impact on pelagic ecosystems is less straightforward.
