| MRAT0012 | Abstraction and flow regulation | The removal of water from the marine environment, and/or the anthropogenic regulation of flow by barrages, wiers or other permanent structures | 2007-06-29 |
| MRAT0005 | Aggregate extraction | The extraction of material from the seabed for economic profit | 2007-06-29 |
| MRAT0011 | Alien species | The introduction of organisms that are not indigenous to a given place or area and instead have been accidentally or deliberately transported to this new location by human activity. | 2007-06-29 |
| MRAT0013 | Climate change | The variation in the Earth's global climate or in regional climates over time. It describes changes in the variability over time scales ranging from decades to millions of years. These changes may come from processes internal to the Earth, be driven by external forces (e.g. variations in sunlight intensity) or, most recently, be caused by human activities. | 2007-06-29 |
| MRAT0017 | Coastal and offshore infrastructure | Physical effects on the water column or seabed caused by coastal and offshore infrastructure (eg marinas, harbours, oil and gas platforms, wind turbines) | 2007-12-05 |
| MRAT0007 | Commercial fishing | The removal of wild fish from the environment by humans | 2007-12-05 |
| MRAT0004 | Dredge disposal | The disposal of material which originates from the seabed | 2007-06-29 |
| MRAT0003 | Dredging | The removal of material from the seabed | 2007-06-29 |
| MRAT0010 | Hazardous substances enrichment | The enrichment of chemicals that are potentially toxic above natural levels | 2007-06-29 |
| MRAT0001 | Land reclaim | Alteration of the state of the seabed for land use | 2007-06-29 |
| MRAT0014 | Litter | The degradation of the environment from waste types consisting of any tangible personal property which has been unlawfully scattered and or abandoned | 2007-06-29 |
| MRAT0020 | Mariculture | The cultivation of marine organisms in their natural habitats, usually for commercial purposes. | 2007-12-05 |
| MRAT0021 | Navigation | Physical effects on the water column or seabed caused by shipping, boating and anchoring. | 2007-12-05 |
| MRAT0018 | Noise | The introduction of noise into the marine environment such as by siesmic surveys, shipping or coastal and offshore infrastructure. | 2007-12-05 |
| MRAT0008 | Nutrient enrichment | The enrichment of nutrients particularly nitrogen species, phosphate and silicate above natural levels | 2007-06-29 |
| MRAT0022 | Operational oceanography | Monitoring activities that are carried out to provide oceanographic forecasts and services to the public and scientific community. They do not provide information on a specific environmental pressure. | 2011-02-24 |
| MRAT0009 | Organic enrichment | The enrichment of carbon based compounds above natural levels | 2007-06-29 |
| MRAT0006 | Shellfish harvesting | The removal of wild shellfish from the environment by humans | 2007-12-05 |
| MRAT0002 | Shoreline reinforcement | Alteration of the coastline for the protection of land from the sea | 2007-06-29 |
| MRAT0019 | Temperature modification | Localised temperature changes caused by human activities such as power stations. | 2007-12-05 |
| MRAT0015 | Unknown | The correct value is not known to, and not computable by, the sender of this data. However, a correct value probably exists | 2007-06-29 |
| MRAT0016 | inapplicable | There is no appropriate value | 2011-08-26 |
