Regional Fisheries Advisory Committee 3rd November, 1986

This is the report from the Regional Fisheries Advisory Committee meeting, which was held on the 3rd November, 1986. The report contains sections on a proposed Haaf Net Limitation order, Salmon and Freshwater Fisheries in the Solway Firth, Ullswater Freshet pumping station, and Authority investigations into Acidity Problems in North West water. Also included is information on commercial salmon fishing in the River Lune and coarse fish close season in enclosed waters. The Fisheries Advisory Committee was part of the Regional Water Authorities, in this case the North West Water Authority. This preceded the Environment Agency which came into existence in 1996.

Problems in estimating the response functions of natural climatic recording systems [abstract]

EXTRACT (SEE PDF FOR FULL ABSTRACT): High-resolution proxy records of climate, such as varves, ice cores, and tree-rings, provide the opportunity for reconstructing climate on a year-by-year basis. In order to do so it is necessary to approximate the complex nonlinear response function of the natural recording system using linear statistical models. Three problems with this approach were discussed, and possible solutions were suggested. Examples were given from a reconstruction of Santa Barbara precipitation based on tree-ring records from Santa Barbara County.
