Sentences with phrase «poc flux»
Efforts to reform the single - sector approach to marine spatial management should incorporate expected climate - induced changes in temperature, oxygenation, pH, and POC flux to the seabed in the development of regional and international management scenarios.

Because the quantity and quality of POC flux is an important ecological forcing factor in the abyss, abyssal ecosystems will be highly sensitive to such changes (Smith et al. 2008, 2009; Tittensor et al., 2011).
Our model outputs suggest that seafloor POC flux will decline in most oceanic areas with exceptions off Peru, the northern coast of Chile, and the Southern and Arctic Oceans (Tables 2, 3; Figures 2, 3).
Reductions in seafloor POC flux will be most drastic, on a percentage basis, in the oceanic gyres and equatorial upwelling zones, with the northern and southern Pacific Ocean and southern Indian Ocean gyres experiencing as much as a 32 — 40 % decline in POC flux (Tables 2, 3; Figures 2, 3).
Recent studies have suggested that the NE Atlantic Ocean could also undergo similar reductions in POC flux (Jones et al., 2014).
These oscillations can produce effects that mimic CO2 - induced changes (e.g., altered upwelling regimes of deep nutrient - rich waters with effects on POC flux; Merino and Monreal - Gomez, 2009).
The continued reduction in the extent of sea ice in the Arctic is expected to lead to increased photosynthetic primary production and POC flux there (Jones et al., 2014), which could benefit fauna whose energetic demands increase as a result of ocean acidification (e.g., calcifying taxa).
Reduced food supply owing to lower POC fluxes could exacerbate these impacts because the metabolic cost of increased rates of calcification become greater as pH declines (Wood et al., 2008).
Not exact matches
If this is taken into account, it can be concluded that POC export fluxes increase while the passing waters are advected around and over the seamount, with the highest export fluxes occurring on the downstream side of the seamount.
