Philip N. Froelich,Gary P. Klinkhammer,Michael L. Bender,Nile A. Luedtke,G.R. Heath,Doug Cullen,Paul Dauphin,Doug Hammond,Blayne Hartman,Val Maynard +9 more
TL;DR: Pore water profiles of total CO 2, pH, PO 3−4, NO − 3 plus NO − 2, SO 2− 4, S 2−, Fe 2+ and Mn 2+ have been obtained in cores from pelagic sediments of the eastern equatorial Atlantic under waters of moderate to high productivity as mentioned in this paper.
Book
The Ecology of Phytoplankton
TL;DR: Reynolds as discussed by the authors provides basic information on composition, morphology and physiology of the main phyletic groups represented in marine and freshwater systems and reviews recent advances in community ecology, developing an appreciation of assembly processes, co-existence and competition, disturbance and diversity.

Flow Injection Analysis
J. Růžička,J.W.B. Stewart +1 more
TL;DR: In this paper, the effect of sample volume, tube length, tube diameter, peak height and sampling rate on the determination of phosphorus in acidic plant digests was investigated, and optimal conditions for the flow injection method were described.

Soil biodiversity and soil community composition determine ecosystem multifunctionality
Cameron Wagg,S. Franz Bender,Franco Widmer,Marcel G. A. van der Heijden,Marcel G. A. van der Heijden +4 more
TL;DR: It is found that reductions in the abundance and presence of soil organisms results in the decline of multiple ecosystem functions, including plant diversity and nutrient cycling and retention, suggesting that below-ground biodiversity is a key resource for maintaining the functioning of ecosystems.

Measurement of microbial biomass phosphorus in soil
TL;DR: In this article, a method for measuring the amount of P held in soil micro-organisms (biomass P) is described and the assumptions on which it is based are discussed.

The storage of sea-water samples for the determination of dissolved inorganic phosphate
J. Murphy,J.P. Riley +1 more
TL;DR: In this paper, a study has been made of methods of preservation of sea-water samples to be analysed for inorganic phosphate, and it is recommended that the filtered samples be treated with 0.7 ml of chloroform per 100 ml of water and stored in the dark in glass bottles.
