DEFRApH-Defining the degree of acidification (pH) of UK waters and potential future changes - ME4133

Description
Key Customer Purpose

This programme of work will provide information without which it will be impossible to assess the potential threat to UK marine waters of acidification resulting from the uptake of increased levels of CO2 into the sea. All the methodologies used will be reported in detail and provide the basis for future developments within the UK’s evolving Marine Monitoring and Assessment Strategy


Summary Objective

A two year long programme of observations will be made in conjunction with existing marine fieldwork programmes at key locations around the UK. This will enable the new information on pH to be set in the context of the variability in hydrographic and biogeochemical conditions that determine the observed pH.
Objective
Objectives:
(1) A two year long programme of observations will be made in conjunction with existing marine fieldwork programmes at key locations around the UK. This will enable the new information on pH to be set in the context of the variability in hydrographic and biogeochemical conditions that determine the observed pH.
(2) A data set will be established of the new data and metadata describing its collection and validation
(3) New data sets will be used to directly determine the pH of a range of seawaters. In addition pH will be estimated over wider range of waters where only partial information is available. These data will establish what present conditions are in the range of water types relevant to the UK from coastal waters to the North Atlantic. To quantify observed and likely variations in pH in time and place with respect to the changes in the ecosystem biogeochemistry and hydrology a numerical analysis of new and existing data will be carried out.
(4) Based on the work carried out to meet objectives 1 to 3, and knowledge of on going developments in measurement technology, recommendations will be made for a future statistically robust programme for monitoring the acidity of UK waters working within UKMMAS-CSSEG framework.
