Nitrogen pools and transformations and benthic communities at a Perna canaliculus farm and a nearby reference site without direct influence of marine farming in Kenepuru Sound, New Zealand, were compared on four dates between September 1982 and May 1983. The organic nitrogen pool in the top 12 cm sediment was 7.4 to 10.8 mol m-2 at the mussel farm and 6.1 to 8.9 mol m-2 at the reference site. The nitrate and nitrite pools were similar in both sediments, but the ammonium pool in the mussel farm… 

Effects of mussel farms on the benthic nitrogen cycle on the Swedish west coast

The biogeochemical impact of 3 long-line mussel farms (M1, M2 and M3) in Lysekil, Sweden, was investigated from before farm establishment until 1.5 yr after operation had begun. Sedimentation,

A multidisciplinary approach to evaluating impacts of shellfish aquaculture on benthic communities

The impact of suspended mussel culture on the benthos of a small Nova Scotia cove was assessed using meehods involving both benthic metabolism and community structure, and there is a shift toward anaerobic metabolism at the mussel lines, the impact of mussels falling to the sediments was more noticeable in benthics community structure than was any impact due to organic sedimentation or hypoxia.

Benthic nutrient fluxes at longline sea squirt and oyster aquaculture farms and their role in coastal ecosystems

To assess the impact of aquaculture activities, we measured the primary production, total sediment oxygen consumption, and benthic nutrient flux at two aquaculture farms (sea squirt and oyster) and

In situ characterization of benthic fluxes and denitrification efficiency in a newly re-established mussel farm.

Amelioration of marine farming impact on the benthic environment using artificial reefs as biofilters.




Sedimentation and sulfate reduction under a mussel culture

The sedimentation and dissimilatory sulfate reduction under a blue-mussel culture were quantified in order to gain information on the environmental impact of intense mussel farming. The sedimentation

Nitrogen cycling in different types of sediments from Danish waters1

Variations in sediment N:C ratios were correlated with water depth and season. 15NH,+ was used to measure the rates of NH,+ production (d) and incorporation into bacterial cells (i) in sediments from

Ammonium adsorption in nearshore anoxic sediments1

The distributions of dissolved, exchangeable, and fixed ammonium were measured in sediment cores from Long Island Sound, Florida Bay, and Pettaquamscutt River, Rhode Island, and in laboratory

Nitrogen, Phosphorus, and Eutrophication in the Coastal Marine Environment

Removal of phosphate from detergents is not likely to slow the eutrophication of coastal marine waters, and its replacement with nitrogen-containing nitrilotriacetic acid may worsen the situation.

Seston transport and deposition in Pelorus sound, south Island, New Zealand

Abstract Transport of seston (suspended sediment) in Pelorus Sound is controlled by tides and freshwater inflow. During high freshwater inflow, a moderately stratified estuarine circulation may be

Method for Measuring Rates of NH4+ Turnover in Anoxic Marine Sediments, Using a 15N-NH4+ Dilution Technique

A method is described for the determination of the net and total rates of NH( 4) production and NH(4) incorporation at different depths in an anoxic marine sediment, which indicated that it was the combined pool that was turning over.

Temporal variability of the waters of Pelorus Sound, South Island, New Zealand

Abstract Dynamics of the flow in Pelorus Sound (41°S, 174°E) are discussed in terms of previously reported observations and new observations in October 1976. Asymmetry in the tidal elevation and flow


A theoretical equation for the photosynthesis-light relation is developed which includes the effects of inhibition in intense light. Assuming 1) that phytoplankton adapts to seasonal light changes

Determination of total nitrogen, phosphorus and iron in fresh water by photo-oxidation with ultraviolet radiation

The photo-oxidation method described by Armstrong, Williams and Strickland for determining total phosphorus and nitrogen in sea water has been adapted for analysis of fresh-water samples and extended

ATP and chlorophyll a as estimators of phytoplankton carbon biomass1

Interspecific differences in both ATP:C and Chl a:C ratios were great enough to suggest that even a cursory examination of phytoplankton species composition could improve estimates of phalassiosira carbon based on ATP or ChlA measurements.
