Description
Observadores del Mar - Seawatchers is an internet platform aimed at connecting citizens and scientists to investigate together the current state of our seas and oceans. Citizens can participate by contributing with their observations and experience. We wish to understand the effects of global warming, pollution, biodiversity changes, invasions of alien species and overfishing in marine ecosystems. To this end, we collect observations and sightings on the distribution and abundance of marine species, the emergence of rare or invasive marine species or the signs of change in ecosystems (mortality of organisms, amassing of surface and bottom pollution).This platform of projects, linked to ongoing research is coordinated by the Institute of Marine Sciences of Barcelona (ICM-CSIC) and relies on the collaboration among citizens scientists from different national and international centers. The main challenges we have are: (1) to detect global warming impacts in biology and distribution of species; (2) to inform about the appearance and expansion of introduced or invasive species; (3) to inform about the presence of warning species such as jellyfish or pufferfish; (4) to expand the knowledge about biology, habitat and distribution of native species; (5) to report the pollution of coasts and sea bottoms and its impact in marine life and ecosystems
Decapod crustaceans (crabs, shrimps, prawns, lobsters, spiny lobsters, hermit crabs,… are a very diverse and still poorly known faunal group, especially so for the wide public. Compared with fish, which are much more evident and easier to watch underwater, crustaceans are much more difficult to obtain reliable information from, since many of them have nocturnal habits, and stay under rocks, buried in the sand or in crevices during most of daytime. Notwithstanding, there is a reasonable number of species that we can be able to see if we watch attentively in the correct habitats, such as crevices or small caves in rocky shores. We aim to obtain data and information on the occurrence not only of the scarce species but also of the common ones. Species that today are common may not be so in a few years time, and inversely, species that today are scarce, or not yet here, may be common tomorrow. Collaboration is necessary and very valuable.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 1,672 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Sampling Methods
Pictures of decapod crustaceans obtained on beaches and rocky shores, as well as submarine pictures taken by divers, observations from sailing boats, etc, Citizen science observations, both casual or scientifically orientated. The minimum information provided by Observers is identification to species level (whenever possible), position (latitude/longitude), and date. Additional information can also be provided (habitat, depth, etc.)
| Study Extent | Mediterranean Sea and adjacent Atlantic Ocean |
|---|---|
| Quality Control | All observations provided by citizens are scientifically validated (or not) to the lowest possible taxonomic level (to species level whenever possible) by a team of scientists/biologists/zoologists that provide also comments and interaction with the observers. |
Method step description:
- (1) Field observation of a decapod crustacean (crabs, shrimps, hermit crabs, lobsters, crawfish,....) (2) Picture taken (3) use of http://observadoresdelmar.es to input the picture with a preliminary identification and associated information. (4) validation of the observation by the scientific team

Additional Metadata
| Purpose | Observadores del Mar, and particularly its section on Decapod Crustaceans was born by a two-way relationship. Scientists need the help of collaborators to obtain additional information on the occurrence, behaviour, habitat, etc. of many marine species from which very little or hardly anything is known. On the other side, citizens often feel the need to let other people know about the observations they make. The feeling that sharing what you see, and of you being useful for other people also provided impulse to create a mechanism that could be useful to both scientists and citizens. Scientists today are well aware of the importance of not keeping to themselves the knowledge obtained during their research, and that by increasing and popularising the knowledge the overall society has on nature, the own society may be further aware of the problems nature has, as well as of the benefits of all kinds nature provides to humankind. In this way scientists obtain further and often simultaneous knowledge, and citizens are rewarded by the acquisition of further knowledge, as well as by the feeling of being useful, which experience says is relevant. |
