FjordStrong are part of a consortium consisting of 20 exceptional project partners, from 12 different countries, collaborating on the EFFECTIVE project. The EFFECTIVE project is a four-year Horizon Europe project dedicated to protecting and restoring the Mediterranean’s Blue Natural Capital across the EU. By integrating advanced scientific research, nature-based technological solutions, digital tools, and social considerations, the project aims to support ecosystem-based management (EBM) of coastal and marine ecosystems.

FjordStrong’s deliverables focus on non-destructive in-situ monitoring for large marine mobile demersal and sentinel species using stereo-BRUVs (Baited Remote Underwater Video systems) following coral reef restoration efforts in an MPA.

The Tavolara Punta Coda Cavallo Marine Protected Area, situated around a small island off the coast of Sardinia, was designated as an MPA in 1997 and implements 3 zones with varied levels of restrictions (A no diving permitted; B; Diving is only allowed with Authorised Diving Centres; & C free and permitted diving).
Representing Pilot 3 in the EFFECTIVE project's MPA network, it is home to one of the most important habitats in the Mediterranean for supporting biodiversity with coral colonies covering approx. 97.2 ha.
The objective for Pilot 3 is to monitor, restore, and conserve coral reefs affected by thermal stress and other environmental threats. This 4-year project focuses on active restoration, led by our passionate collaborators from Coral Soul, who are applying a multi-pronged approach - including relocation, genetic screening and monitoring of stressors.
FjordStrong are conducting in-situ monitoring for marine large mobile demersal and sentinel species (a focus on elasmobranchs), and overall biodiversity. Elasmobranchs can provide insights into the overall health, stability, and biodiversity of coral reefs. Their roles as predators, sensitivity to environmental stressors, and their reliance on coral reef ecosystems make them suitable indicators of coral reef health.
The monitoring surveys use stereo-BRUVs (Baited Remote Underwater Video system), as a non-destructive survey method. An initial baseline survey was conducted prior to the Sardegna Coral Restoration project, to generate a reference index of species in the coral restoration zones and establish a baseline.
We were fortunate to work closely with the MPA management team (www.amptavolara.com) and local dive centre (www.tavolaradiving.it) which were been invaluable in the planning process. Under the guidance of the MPA Director, Pier, baseline surveys were conducted for two sites within Zone A of the MPA: Occhio di Dio and Secca di Papa in March 2023.
These sites were chosen to coincide with the planned coral restoration activities, and to be representative of the varied bathymetry and geology of Tavolara's unique seabed. Control surveys in the same MPA zoning were undertaken, maintaining a similar habitat and bathymetry to the restoration sites. Each control area was >500m away from the restoration sites and ROV transects were performed at every site to ensure no disturbance to the locol coral populations. 
The baseline BRUV survey detected a total of 43 different species, including bluefin tuna, ornate wrasse, hermit crab anemone, greater amberjack and 10 different species of Sparidae (the sea Bream family).
Our annual demersal biodiversity monitoring surveys will be performed at the same time each year, to assess any changes in fish assemblages within the MPA, and any observed changes in patterns will be considered in relation to changes in the surrounding coral reefs.
Watch this space for updates as we continue to monitor the elasmobranchs and biodiversity surrounding the coral reef restoration!

Marine Surveys

We understand our client’s need for robust baseline data as a foundation for the future success of their objectives. Whether it serves as a basis for monitoring the impact of planned infrastructure or the introduction of new management measures, our track record spans diverse marine settings from open ocean to shallow coastal waters and estuaries. Our expert team are committed to using environmentally-friendly, non-destructive and non- extractive methods to generate the data required for the success of your project, from biodiversity indices to oceanographic data. We offer comprehensive support, including survey design, logistical coordination, meticulous data collection, in-depth analysis, and expert report preparation.

Marine Surveys

FjordStrong provides an affordable, zero-impact, reliable solution for measurements of marine specimens in-situ. Using our stereo-imaging cameras, specifically designed to perform in areas of moderate turbidity such as the North East Atlantic, our analysts generate 3D point clouds of the target. With a proven high accuracy at ranges up to 6 metres we offer our clients non-extractive in-situ tool as an alternative to other destructive, lethal and costly methods. Reliable measurements of wildlife can be converted into biomass estimates, condition factors, and determination of developmental stages. Similarly, multi-annual measurements can be used to estimate growth rates, ideal for fragile species such as hard corals.

Marine Surveys

At FjordStrong, our expertise covers taxonomic identification of species and communities, alongside characterisation of the abiotic and physical environment they live in using nationally recognised classification protocols such as JNCC and EUNIS. By collecting data using non-destructive methods such as ROVs and tow-fish cameras, we can systematically identify, predict and compare habitat distribution and ecosystems using a standardised methodology, while preserving the integrity of the area. Such knowledge underpins MPA monitoring, assessing conservation-value of sites, and licensing of industry activities.

Accurate ecological models can inform decision-making and marine management, and collecting reliable and relevant data is the fundamental building block to develop robust ecological models. Our team are trained in advanced video technology and zero-impact methodologies, ensuring precise and comprehensive data acquisition. At FjordStrong we have a track record of generating appropriate input data for models, including but not limited to habitat suitability models, species distribution model, allometric morphological models and oceanographic models. FjordStrong provides the essential data for ecological models that stand up to scrutiny, empowering your organisation with data-driven insights for effective environmental stewardship.

Research

Nature-based solutions present a holistic strategy for tackling environmental challenges, and FjordStrong is committed to incorporating these solutions into marine consultancy. Our team understands the inherent potential of nature-based solutions in cultivating resilience and sustainability in the marine environment and harnessing nature to address both the climate and biodiversity crisis. At FjordStrong, we can integrate nature-based solutions into your unique project needs, from habitat restoration to sustainable blue growth. By taking inspiration from nature, mitigation and adaptive strategies can not only safeguard marine biodiversity, but human well-being and enhance industry sustainability.
