You can be there at the right place and time to find evidence beyond the reach of the scientific community.
Understanding the transformation of the marine environment requires citizen involvement.
Find out about Sea Watchers projects and what you can do for marine science.
Global warming is causing mass deaths of coral and gorgonia, as well as changes to their geographical distribution and reproductive season. Detect signs of its impact.
The arrival of exotic fish may alter the ecological balance and biodiversity of the host area. Identify invasive species and contribute to their monitoring.
Report the presence and abundance of jellyfish. Gather evidence about the dynamics of instances of proliferation on the coast and the arrival of new species so action can be taken.
On the coast or underwater, take photos of crabs, prawns, shrimps and other decapoda in their habitat to study their biodiversity, variations over time and the causes of those changes.
The presence of certain fish is evidence of warming of the water. Find examples of these and other species to study Mediterranean ichthyofauna and its variations.
Identify and photograph the birds you observe at sea at different times of year. This information allows us to know more about their habits and study the conditions that attract them.
Invasive species can displace native species and have an impact on the balance of ecosystems. Send alerts concerning the presence and expansion of invasive algae and help monitor them.
Species such as Posidonia oceanica form seagrass fields that play a crucial role in Mediterranean ecosystems. Gather evidence about their reproduction, biology and ecology, as well as signs of human impact.
Seahorses and pipefish are very sensitive to changes in the environment. Report their presence and the condition of their habitat to study their vulnerability and take conservation action.
A pathogen is wiping out this large mollusc that was already threatened by pollution, fishing and loss of habitat. Observe fan mussels in their environment and report on their health condition.
Overfishing, invasive fish species and climate change are turning underwater forests into areas completely free of algae. Locate these algae-free zones and report on their size.
Plastic accumulated in seas and oceans is a global problem that has an impact on ecosystems. Join the sampling network to measure micro-plastics on beaches and make the problem known.
Maritime traffic, fishing and rivers leave all kinds of waste. Report the waste built up on the seabed and in the water to study its impact on the marine environment and improve its management.
Climate change is rapidly changing the distribution of Mediterranean species and fishes are among the best indicators to monitor this phenomenon. Help us to track their abundance on a regular basis!
Diving clubs, centres, universities and other organisations cover different areas of the coast to perform citizen monitoring of the sea's condition throughout the year.
