Bacterial production of nitrate in aquatic systems: progress report. Nitrate-loss processes in raw water

This short interim progress report builds on previous progress reports which have described the quantification of the process both within and between lakes of different degrees of eutrophication. These data indicated that slight changes in methodology, particularly when investigating sediment deposits, could grossly affect the measured activity. The aim of the present research was an attempt to rationalize these differences. If this could be achieved it would enable meaningful interpretation of published data obtained using different methods and therefore enlarge the available database. In addition some observations have been made on the production of nitrite by Grasmere profundal sediment slurries sampled during the circulation period.

Volunteer Handbook

This Handbook has been prepared to inform you of the National Ocean Service’s history, philosophy, policies, and expectations of you and the NOS. No volunteer handbook can answer every question, so we hope through regular conversations between you and your supervisor we can continue to add to the Handbook as conditions warrant. We hope this Handbook will help you feel comfortable with us. We depend on you in an ever shrinking workforce - your success is our success. Please do not hesitate to ask questions. Your direct supervisor or Volunteer Coordinator will gladly answer them. We ask that you read this Handbook carefully, and refer to it whenever questions arise. The NOS policies, benefits and rules, as explained herein, may be changed from time to time as business, volunteer legislation, and economic conditions dictate. If and when changes are made, you will be made aware of the changes.

Rights first, rights forever: small-scale fisheries and fishing communities from a human-rights perspective. A collection of articles from SAMUDRA report

Small-scale and artisanal fisheries contribute about two-thirds of the global fish production destined for direct human consumption. They also accommodate over 90 per cent of those who make their living from fisheries. Women comprise at least half the workforce in small-scale fisheries. Despite the important contributions made by small-scale fisheries to poverty eradication and food security, small-scale fishers and fishworkers continue to be marginalized at different levels. It is in this context that the Committee on Fisheries (COFI) of the Food and Agriculture Organization of the United Nations (FAO) has developed the Voluntary Guidelines for Securing Sustainable Small-scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines).
