High-Latitude Bioerosion: The Kosterfjord Experiment

Bioerosion is the major force driving the degradation of marine skeletal carbonates and limestone coasts. A wide spectrum of mechanical and/or chemical boring, scraping or crushing organisms break down calcereous substrates, comprising various grazers, ma

Preface The study of bioerosion is situated at the interface between biology (the involved organisms), palaeontology (the borings they leave) and geology (palaeoecology, taphonomy, carbonate degradation and sediment production). Thus, the most promising approach to study bioerosion processes is an interdisciplinary one as well – a principle that has been acknowledged in the design of the Kosterfjord experiment, the first quantitative bioerosion experiment in a non-tropical setting. The targets of this experimental investigation were taxonomical and ecological aspects of bioerosion and their (palaeo)ecological implications alongside quantitative aspects of the carbonate cycling in the cold-temperate setting in the northeastern Skagerrak (SW Sweden). The principal aims of the present volume are twofold: Firstly, I would like to give the reader a reference in hand that reviews the current state-ofthe-art on cold-temperate to polar bioerosion processes and experimental bioerosion studies in general, and secondly, its immediate goal is to present the compiled outcome of the Kosterfjord experiment. This contribution was worked out in the course of my PhD study and acts as doctoral thesis (dissertation) at the Friedrich-Alexander-University Erlangen-Nuremberg. In this conte
