The scaling issue is recognised as a critical hindrance in the translation of climate change science. The project MMS2000+ was a response to this shortcoming. Many coastal zone monitoring systems are intended for use on a local or national scale, and this project facilitated the exchange of data for use on a regional scale. While meteorological parameters tend to be less locally focused, the integration of climate data with real-time in-situ measurements from their many sources is the challenge MMS2000+ addressed, together with developing operational data-assimilation models to produce useful impacts forecasts. Over the last decade, the SeaNet workshop has consolidated this effort across Europe , and evolved in response to other initiatives, such as EuroGOOS, the ocean component of the Global Climate Observation System.
As already mentioned, climate science needs a long-term perspective. The MOLTEN project explores the changes in estuarine and coastal systems arising from human activities through history. Most monitoring programs in the region have only run for a few decades, leaving open the question of when the changes began and what really is the extent of anthropogenic

Differentiates changes that people have introduced to the environment from processes which are natural.

alteration. Palaeoecological analysis of sediments can uncover the long-term effects of nutrient enrichment and how it has affected ecosystem functioning over time. These insights into changes in structure of various parts of coastal and estuarine ecosystems are fundamental for establishing the baseline and time-scale of long-term ecological change.
The general objective of RANR, similar to that of INCA, was to develop improved procedures for regional analysis of the export of nitrogen from land to sea. Its starting point was to identify the minimum amount of information that is required for such analyses (Forsman et al., 1998) outlines the methodological approach). Like other nitrogen studies, it addressed denitrification and the production of nitrous oxide, but its greater value for climate change studies is its approach to developing modelling tools. By taking a process-oriented and mechanistic approach, it integrated water transport processes with nitrogen cycling, in such a way that visualisation technologies and extrapolation tools (e.g., from catchments to regions) can be used and tested.
Denitrification
A process by which oxidized forms of nitrogen such as nitrate are reduced to form nitrites, nitrogen oxides, ammonia, or free nitrogen: commonly brought about by the action of denitrifying bacteria and usually resulting in the escape of nitrogen to the air.

The focus of the SUBGATE project was the transfer of solutes and gases across the sediment-water interface (Figure 2(b)). One of the principle species studied was methane, and this project thus adds to the fundamental knowledge base for carbon cycling and climate change. It explicitly links surface water quality in coastal seas with submarine groundwater fluxes and transport processes. |
