The editors welcome suggestions from potential authors for topics they consider could form the basis of future appropriate contributions. Because an annual publication schedule necessarily places constraints on the timetable for submission, evaluation and acceptance of manuscripts, potential contributors are advised to contact the editors at an early stage of preparation. Contact details are listed on the title page of this volume. The editors gratefully acknowledge the willingness and speed with which authors complied with the editors’ suggestions, requests and questions, and the efficiency of Taylor & Francis in ensuring the timely appearance of this volume. 7044_C000.fm Page viii Tuesday, April 25, 2006 1:51 PM 7044_C000.fm Page ix Tuesday, April 25, 2006 1:51 PM Correction to Volume 43 Carney, R.S. 2005. Zonation of deep biota on continental margins. Oceanography and Marine Biology: An Annual Review 43, 211–278. In reviewing various ideas put forward to explain deep benthic depth zonation (Carney 2005), the TROX, Trophic-Oxygen, model for foraminiferan distributions received special mention. This conceptual model incorporates in an easily understood manner several lines of thought concerning the importance of oxygen and labile carbon influx in controlling surficial and interstitial microhab- itats. The origin of the TROX model, however, is misattributed to Loubere and his associates (page 228). The TROX model was proposed in the context of microhabitats with Adriatic transect data used as an example by Jorissen et al. (1995). An important feature of the TROX model is the explicit link between oxygen and carbon flux, such that the ecological importance of food avail- ability changes with oxygen concentration. Given adequate oxygen, food is the primary factor. When microbial consumption of higher food levels reduces microhabitat oxygen, then low oxygen can become the primary factor. There have been other attempts to create general foraminiferan distribution models that incorporate both oxygen and carbon flux somewhat similar to TROX. An algebraically formal model of gradient distribution employing the concept of ‘r’ and ‘K’ selected species was developed by Sjoerdsma & van der Zwaan (1992) and tested with mixed success on archived distribution data from the Gulf of Mexico. Unfortunately, the geochemical relationship between oxygen and carbon flux was omitted. Bottom oxygen was estimated from water column profiles, and flux estimated only on the basis of depth. The conceptual model proposed by Loubere et al. (1993) was an assemblage model incorporating both production and taphonomy. Like the TROX model, it is an important contribution to the understanding of trophic control of geographic distribution. That mode links the geochemistry of oxygen and carbon flux. Flux was estimated from sedimentary oxygen consumption; samples were analysed from the western Gulf of Mexico. REFERENCES Carney, R.S. 2005. Zonation of deep biota on continental margins.

PART II: MODEL VALIDATION AND DATA NEEDS GÜNTHER RADACH & ANDREAS MOLL Institut für Meereskunde (IfM), Universität Hamburg (ZMK-ZMAW), Bundesstr. 53, D-20146 Hamburg, Germany E-mail: [email protected], [email protected] Abstract The aim of this review is to provide an overview of the status of validation of eleven biogeochemical and ecological models of the greater North Sea (COHERENS, CSM-NZB, DCM- NZB, DYMONNS, ECOHAM, ELISE, ERSEM, FYFY, GHER, NORWECOM, POLCOMS- ERSEM) showing the realism achieved as well as the problems hindering a better degree of validity of the models. Several of the models were able to reproduce observations of the state variables correctly within an order of magnitude, but all models are not capable of reproducing every simulated state variable in the range of observations. None of the models can be called a valid model. Comparison of results from different models with datasets are evaluated according to the different spatial and temporal scales, for which data products were available, namely for regional distributions, annual cycles, long-term developments and events. The higher the trophic level, the greater was the discrepancy with the data. Problems still exist in determining the necessary com- plexity of the ecosystem model. More complexity in the model does not necessarily improve the simulations. Special
