Canyon of Caprera

A research project aimed at protecting a key biodiversity hotspot in the Mediterranean Sea through scientific activities with a focus on marine mammals and long-term conservation efforts.

Since 2019, One Ocean Foundation is dedicated the protection of the Canyon of Caprera, home to the largest submarine canyon system in northeastern Sardinia, in the central Tyrrhenian Sea.


The initiative aims to gather scientific evidence to promote effective conservation measures, such as the designation of a Fisheries Restricted Area (FRA) and a Marine Protected Area (MPA).

To achieve this goal, the Foundation collaborates with research institutions, universities and local associations to collect critical data on the ecology of the area and the distribution of cetaceans, key indicators of marine ecosystem health.



Why it matters

  • The Canyon of Caprera is a biodiversity hotspot and a strategic crossroads in the Tyrrhenian Sea.
  • Despite being adjacent to protected areas, the Canyon currently has no official protection, leaving its biodiversity at risk.
  • The area is increasingly threatened by human activities, such as maritime traffic and fishing.

GOALS


The main goal of this project is took build solid scientific knowledge to support the protection of the Canyon biodiversity, with the ambition of achieving its recognition as an Important Marine Mammal Area (IMMA) and a Fisheries Restricted Area (FRA), paving the way towards the designation of a Marine Protected Area (MPA).

Thanks to years of dedicated research and advocacy, the Canyon of Caprera has been officially nominated as a Hope Spot®, a recognition granted by oceanographer Sylvia Earle’s Mission Blue initiative. Today, the area joins the global network of more than 140 Hope Spots® and stands as the second one in Italian waters, following the Aeolian Islands.

Research activities

Visual & ROV Surveys

Photo-identification at surface to track the presence, distribution, and habitat use of marine mammals, and underwater surveys with ROVs to study vulnerable deep-sea ecosystems, assess benthic communities, and detect potential threats.

Acustic Monitorig

Investigating the spatiotemporal distribution of deep-diving cetaceans and other key species to better understand ecosystem dynamics and habitat use.

Molecular Analyses

Assessment of biodiversity in the canyon through the collection and analysis of environmental DNA (eDNA), covering both species and habitat composition.

Eco- toxicological Assessment

Evaluation of pollutants and trace metals in marine organisms to assess contamination levels and potential impacts on canyon’s biodiversity.

Results

240field expeditions
11.7Kindividuals recorded
40eDNA samples collected
40zooplankton samples collected
16pollutants classes analyzed
1.1Khours of acoustic recordings
7 ROV dives

ROV dives conducted between 200m and >1,000m depth allowed us to observe 16 deep-sea benthic species, survey 2.6 km of seabed linearly, and complete 11 hours and 40 minutes of useful deep-sea video footage.
