Description of Activities


The main aim of this activity was to ensure long-term feasibility of the monitoring processes.

Service Contract CT 3031/2016 implemented selected monitoring processes including those covering the following themes:

Water Column Habitats

Water column habitats are generally referred to as “pelagic” habitats, and include the water column and all the organisms that inhabit it. Monitoring of such habitats focused on the composition, abundance and biomass of communities of phytoplankton and zooplankton, which are microscopic organisms which form the base of food chains within the water column and are therefore key indicators of the condition and health status of this habitat. Physiochemical and hydrological parameters were also monitored.

Seabed Habitats

Seabed, or benthic, habitats are defined based on the physical substrate, hydrological characteristics such as temperature, salinity and water movement, and the composition of species communities associated with the seabed, as well as species present.

The project monitored selected seabed habitats such as macroalgae along the coastline, seagrass beds and maerl beds, to assess their extent and condition, through the assessment of benthic species living in the sediments.

Non-Indigenous Species

Non-indigenous species are also known as alien species; species that have been introduced outside of their natural range and their natural dispersal potential, intentionally or unintentionally as a result of human activities. These species may threaten or adversely impact local biodiversity and related ecosystem services.

The project monitored the occurrence of non-indigenous species in Maltese Marine Protected Areas (MPAs) and hotspots, while also providing an indication of the abundance of selected species groups, including phytoplankton and zooplankton communities in the water column habitats. This monitoring enabled an assessment of the pressures arising from non-indigenous species in Maltese waters and will identify appropriate management measures to be taken.


Increased levels of certain nutrients in the marine environment, generally nitrogen and phosphorus, can lead to enhanced primary or biomass production. This can result in reduced light penetration in the marine environment and increased carbon fixation, resulting in algal blooms, and changes to the taxonomic composition of algae and plants. The consequences of this process, called eutrophication, are undesirable since they can degrade ecosystem health and/or the sustainable provision of goods and services, apart from being visually unattractive. Increased levels of organic matter in the marine environment are also associated with negative effects on the marine environment.

The project monitored nutrient levels in the water column and organic matter in the sediment, as well as the effects of eutrophication through links with other monitoring processes.

Hydrographical Changes

The physical parameters of seawater – temperature, salinity, depth, currents, waves, turbulence and turbidity – change as a result of large scale human activities, such as coastal defence works and structures in coastal or open sea which can permanently influence the hydrographical regime of currents, waves and sediments. These changes can in turn induce further changes to sediment transportation, seabed structure, salinity and temperature which might lead to effects on marine ecosystems as a result of changes to their immediate dynamic environment or through food chain effects.

In addition to the physical characteristics of the water column, the project also included spot measurements of current profiles. The data collected will feed into hydrographical models that will be developed through other EU funded projects with the aim to learn more about the baseline conditions of Maltese waters, thereby enabling the monitoring of these baseline conditions.


Contaminants or hazardous substances are defined as chemical elements and compounds or groups of substances that are toxic, persistent and liable to bioaccumulate, and other substances or groups of substances which give rise to an equivalent level of concern.

Hazardous substances can be broadly classified into two principal groups: synthetic substances and non-synthetic substances. Synthetic substances refer to compounds such as pesticides, pharmaceuticals and anti-fouling agents; whereas non-synthetic substances include naturally occurring substances such as trace metals, aliphatic and aromatic hydrocarbons, as well as by-products of combustion activities.

Through this project, a selection of contaminants listed in the Priority Substances Directive 2013/39/EC as well as other contaminants of national concern, were monitored in water, sediments or biota.

Marine Litter

Marine litter is defined as ‘any persistent, manufactured or processed solid material discarded, disposed of or abandoned in the marine and coastal environment’. Based on this definition therefore, marine litter consists of items made or used by people, such as plastics, wood, metals, glass, rubber, clothing and paper, discarded in the sea and on beaches, deliberately or unintentionally.

This project monitored the characteristics and abundance of the marine litter which is present in the water column and on the seabed, as well as marine litter washed ashore.

These monitoring programmes were updated on the basis of the data collected, so as to address any shortcomings in the established monitoring procedures and increase the efficiency of the project’s monitoring efforts. The final monitoring report can be found here.

Additional monitoring and assessment in 2020 and 2021 will focus on:

Marine Mammals and Reptiles

There are a few confirmed species of marine mammals (or cetaceans) that regularly occur in Maltese waters. These include the bottlenose dolphin (Tursiops truncatus), the common dolphin (Delphinus delphis) and the striped dolphin (Stenella coeruleoalba). Other cetacean species which are occasionally sighted include the Risso’s dolphin (Grampus griseus), the fin whale (Balaenoptera physalus), the Cuvier’s Beaked whale (Ziphius cavirostris) and the sperm whale (Physeter macrocephalus). 

Marine reptiles on the other hand are represented by one species in Maltese waters: the loggerhead turtle (Caretta caretta).

Three Marine Protected Areas have been designated for the conservation of Tursiops truncatus and Caretta caretta in Malta’s Fisheries Management Zone (MT0000113, MT0000115 and MT0000116), which areas were adopted as Natura 2000 sites in accordance with the EU Habitats Directive 92/43/EEC. The designation of these Marine Protected Areas was based on systematic surveys carried out through the LIFE+ MIGRATE project in the summers of 2013 and 2014.

The project will seek additional monitoring data on marine mammals and marine reptiles in Maltese waters with the aim to substantiate previous data and achieving long-term monitoring processes for marine mammals and marine reptiles as required by the EU Marine Strategy Framework Directive (2008/56/EC) and Habitats Directive (92/43/EEC).


Malta is considered to be an internationally important breeding location for three seabird species, Scopoli’s Shearwater (Calonectris diomedea), Yelkouan Shearwater (Puffinus yelkouan) and the European Storm-petrel (Hydrobates pelagicus). The coastal cliffs and screes, which predominate along the southwestern coast of the archipelago provide shelter and a breeding habitat to these seabirds.

Data used for assessment and conservation of these species has to date been primarily collected by independent researchers and through EU funded projects led by BirdLife Malta in particular the LIFE+ Malta Seabird Project (LIFE10 NAT/MT/090 – 2011-2016) and the LIFE Archipelagu Garnija Project (LIFE14 NAT/MT/000991 – 2015-2020). A continuous data collection process for these seabirds however needs to be ensured to enable assessment of trends and the conservation status of these species in accordance with the requirements of the EU Marine Strategy Framework Directive and the EU Birds Directive.

This project will seek to address the MSFD and Birds Directive requirements by developing and implementing a monitoring strategy for seabirds in Malta, building on Malta’s MSFD monitoring programme, that can be implemented on a continuous basis in the long-term and enable continuous assessment of status.

Food Webs

Marine food webs refer to networks of marine organisms linked by feeding interactions. The exchanges of energy and nutrients through the food chain reflect the functioning of ecosystems. Anthropogenic activities can cause changes to the structure and dynamics of the food webs, thus affecting ecosystems as a whole.

The EU Marine Strategy Framework Directive 2008/56/EC (MSFD) addresses ecosystem aspects through food webs by dividing the structure and function of food webs into compartments which share common features, i.e. ‘trophic guilds’. Trophic guilds may refer to important prey groups (defined by who eats them) as well as predators (a group that eats the same thing).

This project will seek the establishment of a monitoring protocol for trophic guilds in Maltese waters through the identification of indicator species and collection of baseline data for the purpose of establishing long-term monitoring processes in line with the requirements of the EU Marine Strategy Framework Directive (2008/56/EC). This assessment would enable the long-term monitoring of ecosystems and shed light on their status, thus contributing to better implementation of ‘an ecosystem-based approach’ to management.

The main aim of this activity was to ensure access to data to all relevant stakeholders with a view to facilitate management of the marine environment across sectors.

The project has created a robust database system from which INSPIRE-compliant datasets can be extracted. This is linked with ERA’s data platform, housing raw and analysed monitoring data.
The database facilitates access to relevant information, allowing the public to understand the status of the marine environment and follow the country’s progress towards the achievement of good status.

The datasets for QGIS can be accessed from here.

The main aim of this activity was to analyse monitoring data, assess environmental status and propose environmental targets throughout the duration of the project with a view to bridge monitoring data with management regimes.

The implementation of the monitoring processes as per service contract CT 3031/2016 was initiated in July 2017 and was completed in March 2019.The data collected as part of this service contract was analysed on the basis of established criteria and indicators. This analysis is presented in an assessment report that includes an indication of the environmental status of Malta’s marine waters in line with the Marine Strategy Framework Directive’s Annex I descriptors.

The assessment of status is based on criteria and indicators, and associated thresholds established by processes or guidance documents pertaining to the EC Habitats Directive (92/43/EEC), the Water Framework Directive (2000/60/EC), the Marine Strategy Framework Directive (2008/56/EC), and the newly revised Commission Decision 2017/848, and works towards streamlining the status definitions across these documents.

The final assessment report for the themes covered by Service Contract CT 3031/2016 can be found here.

Other targeted monitoring processes for marine mammals, marine reptiles, seabirds and trophic guilds will be sought through separate procurement processes as part of the project. These monitoring processes require further development prior to implementation, and experts’ assistance will be sought through this project to establish long-term monitoring processes that will be tested though implementation, on the basis of which long-term monitoring will be maintained for the purpose of assessment of environmental status.

The main aim of this activity was to develop and implement a communication strategy to target the dissemination of information on the status of the marine environment on the basis of monitoring data (Activity 3) and the marine database system (Activity 2).

The service contract CT 3031/2016 project foresaw a series of communication events and tools aimed at disseminating information on the outcome of the project. There have been a number of features on radio and TV programmes as well as three press releases in March and July 2017, and April 2018.
