Sentences with phrase «in coastal ecosystems»

However, changes in pH in coastal ecosystems result from a multitude of drivers, including impacts from watershed processes, nutrient inputs, and changes in ecosystem structure and metabolism.

It will consist of sensor arrays anchored in coastal ecosystems, polar regions and around the entire Juan de Fuca tectonic plate in the Pacific Northwest of the US, allowing scientists to observe volcanic activity and earthquakes as they happen.

Former President Barack Obama in 2014 made research on understanding carbon dynamics in these coastal ecosystems a priority because of their importance to the global carbon cycle.

Environmental drivers of heterogeneity in the trophic - functional structure of protozoan communities during an annual cycle in a coastal ecosystem.

The bizarre mass migrations, though, form an important link in the coastal ecosystem here.

Despite the critical role they play in coastal ecosystems, vast tracts of mangrove forests are commonly cleared to make way for shrimp ponds or beachfront developments.

FOERDIA's findings match those of a 2015 study carried out by the Center for International Forestry Research (CIFOR) that calculated Indonesia's mangroves as storing 3.14 billion tons of carbon — a third of the carbon stored in coastal ecosystems worldwide.

ESM 254 - Coastal Marine Ecosystem Processes [4 units] Lenihan Examination of physical, chemical and geological processes in coastal ecosystems, including estuaries, that are influenced by human activities.

This article is from Hakai Magazine, an online publication about science and society in coastal ecosystems.

Benthic microbial processes can also modify alkalinity and pH through sediment — water fluxes in coastal ecosystems (Cyronak et al. 2013).

The strong controls that ecosystem metabolism and watershed processes exert on the pH in coastal ecosystems suggest that strategies based on the management of ecosystem components and watershed processes may help buffer the impacts of OA by anthropogenic CO2 locally, an option not available for the open ocean.

The reason for this conclusion is that, unlike the open ocean, pCO2 in coastal ecosystems is not necessarily in equilibrium with the atmosphere at even annual timescales and many coastal ecosystems emit CO2 into the atmosphere (Laruelle et al. 2010; Cai 2011).

Hence, paradoxically, we lack guidance on the future trajectories of pH in coastal ecosystems where some of the most vulnerable taxa to OA live (e.g. Doney et al. 2010; Hendriks et al. 2010a; Kroeker et al. 2010).

pH variability in coastal ecosystems.

«Until now, a lack of information and monitoring has been a major impediment to understanding the extent and impacts of «dead zones» and eutrophication in coastal ecosystems,» said Mindy Selman, senior water quality analyst at WRI, in a press release.

The model covers a multitude of social, ecological and economic effects, e.g. beach erosion, inundation of coasts, storm surge damages, migration of affected people, changes in coastal ecosystems and the penetration of salt water into the lower reaches of rivers.

Thus, predictions of future trajectories of pH in coastal ecosystems are still highly uncertain even though model predictions can provide reliable predictions for the future trajectories of open - ocean pH and, thereby, the open - ocean end - member affecting coastal pH. Moreover, we argue that even the expectation that the component of coastal pH change associated with OA from anthropogenic CO2 will follow the same pattern as that in the open ocean is not necessarily supported.

The Blue Carbon Initiative currently focuses on carbon in coastal ecosystems - mangroves, tidal marshes and seagrasses.

Seepage of groundwater can lead to areas of high pCO2 and low pH in coastal ecosystems (Basterretxea et al. 2010).

Whereas these effects on open - ocean pH are calculated to be minor, they can be higher, at rates of 0.02 — 0.12 × 10 − 3 pH units per year (< 10 % of OA by anthropogenic CO2), in coastal ecosystems (Doney et al. 2007), where atmospheric deposition is intense and the waters can be more weakly buffered.

Furthermore, in coastal ecosystems, the detection of trends towards acidification is not trivial and the attribution of these changes to anthropogenic CO2 emissions is even more problematic.
