E d i t e d b y D. V. E l l i s Marine Pollution Bulletin will publish records of university theses relevant to marine pollution in the format shown below. Theses can be from any relevant discipline such as Biology, Chemistry, Engineering, Medicine, Economics, etc. Contributions should be 50-100 word descriptions of thesis content, with emphasis on the marine pollution aspects. They should be sent to the Thesis Record editor (Dr. D. V. Ellis, Biology Department, University of Victoria, Victoria, B.C., Canada V8W 2Y2), with a copy of the officially endorsed thesis title page and abstract. Copy of a title page alone may be submitted (by any interested person) in which case the record will consist of author, year, title, degree, university and supervisor. Contributions should be for theses accepted for M.Sc. or Ph.D. degrees during the past five years, although in exceptional circumstances a contribution recording an older thesis will be accepted for publication.

important subdivisions. The regions identified have been shown either to be controlled by anthropogenic inputs or to reflect mainly the effects of natural forces• Although disturbance effects due to anthropogenic inputs are suggested through the biosedimentary approach, the estuary as a whole cannot be considered badly polluted. However, defaunated, impoverished and over-enriched areas appear as a result of localized severe pollution indicating the need to improve effluent treatment systems• Correspondence to: Dr. A. M. J.

WANC, Juying. 1992• Some Aspects on the Toxicity of the Species of Heavy Metals to Phytoplankton. M.Sc., Ocean University of Qingdao (Supervisor: Dr. Manping Zhang). The toxicity of Cu, Cd, Pb and Zn to marine algae Dicrateria and Phaeosactylum was studied in seawater medium. A model reflecting the relation between toxicity and the concentration of added metals was given. The relation of tx and Ccd was studied and the inhibition model was considered to be: ix-

The combined toxicity effects of Cu, Cd, Zn and their mechanism depends on alga species, metals and the concentration ratio of two metals. The effect of 20 amino acids on the toxicity of Cu, Cd and Zn was also

The metal ions can also change the normal structure of mitochondria and make the size of algae larger.

1991. Investigations of the horizontal distribution of selected trace metals in the Atlantic Ocean. Ph.D. Alfred-Wegener-Institute for Polar and Marine Research Bremerhaven/University of Bremen (Supervisor: Prof. Dr. W. Ernst). The thesis contains data of several projects performed on three expeditions of RV Polarstern during the Atlantic Ocean between 50°N and 50°S. With the aid of a newly developed surface water sampling system some 300 open ocean surface seawater samples were collected. Analysis generated high resolution data sets of Al, Cd, Cu, and Pb. Additional sampling of marine rainwater samples allowed modelling of transport and seasonal variation of trace metal fluxes into seawater via the atmosphere. Anthropogenic and terrigenic sources were discussed and identified. Another project dealt with sampling of suspended particulate matter in parallel by a continuous centrifuge. Contents of AI, Cd, Cu, Fe, Mn, and Pb in SPM reflected biogeochemical cycles and dynamics of partition of trace metals between dissolved and particulate phases over a wide geographical range. The speciation of Cd in seawater was studied by a new direct electrochemical approach. HELMERS, E.
