Solent Bass Pre-recruit Survey (FSS: SOLENT)

There are over 50 surveys in this series which began in 1983. The aim of these 
are to provide abundance indices of 2-4 year old bass. The catch density of 
other species taken is also recorded. The survey was undertaken twice yearly 
during May and September for most years up to 2009. Since then one September 
survey each year has taken place.

The abundance, age and length of bass is recorded from fishing stations on a 
standard grid in Southampton Water, the Solent, and Portsmouth and Chichester 
Harbours using a standard bass trawl. A QA exercise has been undertaken in 
February 2014.

WFD Cycle 2 trac DIN classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Winter Dissolved Inorganic Nitrogen (Winter DIN) in transitional and coastal water bodies. Physico-chemistry, in this case Winter DIN, is a supporting element that underpins the ecological status of a transitional or coastal water body. Data consisting of Winter DIN, salinity and Suspended Particulate Matter (SPM) records are run through the Winter DIN Water Framework Directive (WFD) classification tool. The actual (observed) values of Winter DIN are compared with a predicted value, using a different method for Clear water bodies and Not-Clear water bodies (these categories are based on average SPM). Clear waters are classified using the predicted relationship between average Winter DIN and average salinity in pristine waters; not-clear waters are classified using the predicted relationship between a 99%ile value of Winter DIN and average SPM in pristine waters.  The comparison between the observed and expected values of Winter DIN is used to produce a Winter DIN classification (High, Good or Moderate only) of a transitional or coastal water body for WFD purposes.

WFD Cycle 2 river hydrology classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for hydrological regime. A river can only hold a healthy biological population if there is sufficient water and natural structures to support biological processes. Rivers with sufficient flows can also support human activities such as farming, drinking water supply and industrial processes. The hydrology assessment tool uses data on freshwater flows, physical modification and water abstraction to assess the health of a water body. The tool works by assessing a water body’s compliance category (freshwater inputs less abstraction amounts) against a score for flow compliance. 
A water body cannot score high status if it is considered to be ‘heavily modified’ which refers to a river being modified from its natural state for human use. If a water body considered heavily modified scored high in the compliance and flow tests it would be automatically downgraded to ‘Supports Good’ status.
Flow, abstraction and physical structure data are used in combination to produce scores known as Ecological Quality Ratios (EQR). EQRs are used to produce a Hydrology classification (High, Supports Good, Good, Moderate, Poor, Bad) of the water body for Water Framework Directive (WFD) purposes.

WFD Cycle 2 lake salinity classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Salinity in lakes.

Salinity is a supporting element and is an ecological factor of considerable importance, influencing the types of organisms that live in a body of water. Salinity also influences the kinds of plants that will grow either in a water body, or on land fed by water.
The tool used to provide Salinity classifications uses electrical conductivity or "reference conductivity", as a proxy for salinity. 
The classification method is applied to all lakes with conductivity data within the classification time window and those that are not naturally influenced by saline water ie those not in Brackish type. 
Classification bands are applied as part of classification are Good or Not Good dependent on the average of the reported conductivity within each waterbody. Attribution statement: © Environment Agency copyright and/or database right 2015. All rights reserved.

WFD Cycle 2 lake littoral invertebrates classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Macro-invertebrates in lakes. Lake acidification macro invertebrate metric (LAMM) is a species/ abundance weighted method that assesses the degree to which anthropogenic acidification has impacted macro-invertebrate communities. Results are compared to reference conditions (ie. Non-impacted) and the index quantifies the deviation from pristine status via an Ecological Quality Ratio (EQR). Two sets of reference conditions are used for Humic & Clear waters. 
Classification bands are applied from High (little or no impact) to moderate or worse (significantly impacted).  Confidence of class (CoC) is also calculated. This gives the likelihood of the site belonging to any particular class for WFD reporting. Attribution statement: © Environment Agency copyright and/or database right 2015. All rights reserved.

WFD Cycle 2 lake chironomids classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for Chironomids in lakes. Chironomid populations within any given waterbody closely reflect both the nutrient and pH conditions within the water body. Scoring systems that allow the impact of both pressures to be assessed have been developed. However, currently only the CPET nutrient scoring system has been through intercalibration and is used for water body classification under the Water Framework Directive (WFD).
CPET is an important tool for monitoring large water bodies. Its passive sampling methodology, compared with the direct sampling methods used in all other ecological techniques makes it particularly good for representing ecological function and providing classification at a waterbody scale.
The tool uses a series of predictor variables to produce a reference chrionomid community for the waterbody, which it then compares with the observed chrionomid community to produce an EQR value. Attribution statement: © Environment Agency copyright and/or database right 2015. All rights reserved.

WFD Cycle 2 ecological water body classification

Ecological status classifications can be composed of up to five different assessments:
1. An assessment of status indicated by a biological quality element such as fish, invertebrates or algae.
2. An assessment of compliance with environmental standards for supporting physico-chemical conditions, such as dissolved oxygen, phosphorus or ammonia.
3. An assessment of compliance with environmental standards for concentrations of specific pollutants, such as zinc, cypermethrin or arsenic
And, in determining high status only:
4. A series of tests to make sure that hydromorphology is largely undisturbed
5. An assessment of the presence of invasive species.
Ecological status is recorded as high, good, moderate, poor or bad. ‘High’ represents ‘largely undisturbed conditions’. Other classes show increasing deviation from undisturbed or reference conditions.  Ecological status is determined by the worst scoring element (one-out-all-out approach).

WFD Cycle 2 coastal phytoplankton classification

This dataset is a subset of "WFD Classification Status Cycle 2" and contains classification data for phytoplankton in coastal water bodies.  Phytoplankton are microscopic primary producers and form the basis of the food chain. They utilise sunlight energy and dissolved nutrients converting these into organic materials which are often consumed by higher life forms such as fish. As phytoplankton are short lived and derive their nutrients from the water; they are an ideal indicator of changing nutrient conditions and therefore useful for assessing pollution of coastal waters

 In natural waters a high number of different species of phytoplankton would be expected with high levels of growth in the spring and autumn (blooms). There would be a natural population decline due to nutrient depletion and grazing pressures in the summer. Phtyoplankton population data, group succession and chlorophyll data are used in combination to produce scores known as Ecological Quality Ratios (EQR). EQRs are used to produce a Phytoplankton classification (High, Good, Moderate, Poor, Bad) of the water body for Water Framework Directive (WFD) purposes.
