Abstract. One of the major features of the coastal zone is that part of its sea floor receives a significant amount of sunlight and can therefore sustain benthic primary production by seagrasses, macroalgae, microphytobenthos and corals. However, the contribution of benthic communities to the primary production of the global coastal ocean is not known, partly because the surface area where benthic primary production can proceed is poorly quantified. Here, we use a new analysis of satellite…

Benthic microalgae (BMA) inhabit the upper few centimeters of shelf sediments. This review summarizes the current information on BMA communities in the South Atlantic Bight (SAB) region of the

Global seaweed productivity

The magnitude and distribution of net primary production (NPP) in the coastal ocean remains poorly constrained, particularly for shallow marine vegetation. Here, using a compilation of in situ annual

Importance of coastal primary production in the northern Baltic Sea

The main reason for this discrepancy is the lack of data regarding benthic primary production in the northern Baltic Sea, but also that past studies overestimated the importance of pelagic primary production by not correcting for system-specific bathymetric variation.

Survival in low light: photosynthesis and growth of a red alga in relation to measured in situ irradiance

The findings reinforce the importance of understanding the physiological response of macroalgae at the extremes of environmental gradients and highlight the need to establish minimum thresholds that modification of the subtidal light environment should not cross.

Effects of ocean acidifi cation on benthic processes, organisms, and ecosystems

The benthic environment refers to the region defi ned by the interface between a body of water and the bottom substrate, including the upper part of the sediments, regardless of the depth and

Light Limitation within Southern New Zealand Kelp Forest Communities

This study suggests that commonly used metrics such as species diversity and density are not as sensitive as direct measures of biomass when detecting the effects of light limitation within macroalgal communities.

Contribution of boulder reef habitats to oxygen dynamics of a shallow estuary.

Tidal modulation of seabed light and its implications for benthic algae

The temporal behavior of seabed light in a shallow, tidal sea is set largely by the interaction of the solar elevation cycle with tidal cycles in water depth and temporal variability in water

Important contribution of macroalgae to oceanic carbon sequestration

The role of macroalgae in Blue Carbon assessments has been controversial, partially due to uncertainties about the fate of exported macroalgae. Available evidence suggests that macroalgae are




The coastal zone is where land, ocean, and atmosphere interact. It exhibits a wide diversity of geomorphological types and ecosystems, each one displaying great variability in terms of physical and

Contribution of benthic microalgae to ice covered coastal ecosystems in northern Hokkaido, Japan

Benthic microalgal communities usually make a major contribution to the primary production of estuaries and shallow seas. Pulse amplitude modulation (PAM) fluorometry was used to investigate the

Zooplanktivory by a nocturnal coral‐reef fish: Effects of light, flow, and prey density

The in situ rate of zooplanktivory by a common, nocturnal coral-reef fish, Apogon annularis, was measured to assess the effects of light, prey density, and flow on the fish’s predation and it was demonstrated that Nocturnal vision in A. Annularis is sufficiently sensitive to allow a remarkable detectability of large prey in its natural habitat.

Benthic diatoms of a high Arctic fjord (Young Sound, NE Greenland): importance for ecosystem primary production

Patches of benthic diatoms covered 23 to 73% of the sediment area at water depths down to 30 m of a high Arctic fjord system (Young Sound, NE Greenland). Mapping of the in situ chlorophyll (chl a)

Is Total Primary Production in Shallow Coastal Marine Waters Stimulated by Nitrogen Loading

The global nitrogen cycle has been extensively modified by human activity to the extent that more N is fixed annually by human-driven than by natural processes (Vitousek 1994). This alteration

Primary productivity of reef-building crustose coralline algae

The primary productivity of four species of crustose coralline algae was measured as a function of depth (0–18 m) and irradiance on samples collected from and growing upon the windward coral reef at

Primary production potential of non-geniculate coralline algae at Cape Evans, Ross Sea, Antarctica

Coralline algae at Cape Evans are able to persist with net carbon accrual under ice, while being able to tolerate periods of higher irradiance during ice-free conditions, which contrasts to Phyllophora antarctica which is dependent on ice- free periods to achieve net production.
