For the first time, short-chain organic acids are described in interstitial waters from sediments and lithified materials in a backarc setting. Organic acids in interstitial waters from the Tonga forearc region were also analyzed and compared with previous organic acid analyses from the Mariana and Bonin forearc interstitial waters. In the Tonga backarc setting, propionate typically dominates the organic acid assemblage, and organic acids are a consistent feature of these interstitial waters. The persistent presence of ammonia and the dominance of propionate over formate in the backarc interstitial waters suggest that the organic acids in this setting have their origin in reductive deamination of amino acids derived from sedimentary proteinaceous material. The organic acid assemblage revealed in the samples from Hole 841B in the Tonga forearc are similar to the organic acid assemblage detected in the Mariana forearc, that is, formate dominates the assemblage over acetate or propionate. These forearc organic acid assemblages may both have formed by a similar mechanism.

This book offers a framework for the influence of context on evaluation practice and is applied to three case studies: environmental context; indigenous context and political context; and finishes with a process for implementation.

To be able to carry out physical, chemical and biological investigations on a lake, one needs a thorough knowledge of the volume of water and the shape of the lake basin. Little is known about the about the morphology of the lakes in Schleswig-Holstein and its ecological consequences. For this research a 30 KHz echo sounder with sediment transceiver was used to carry out profile determinations (echo soundings). This apparatus continuously records on paper the different reflexions and absorptions of the sediment and water body in the corresponding depth. By this, acoustically noticeable layers and different densities in the sediment and 'scattering layers' in the water body due to physical, chemical and biological reasons (e.g. plans and single fish) are made visible. Result are summarised here regarding the echo soundings in Blunker See.
