Plankton Trail

The plankton trail is the new tool of the participative objective plankton program.

océanopolis proposes a playful scientific walk to discover plankton in augmented reality. These "virtual fishermen" equipped with their smartphones and thanks to the mobile application "Street science" will be able to collect plankton and discover the richness of the roadstead of Brest.

To play, the walkers go on the mobile application and choose "objective plankton in the roadstead of Brest", they are then invited to scan 10 signs positioned from the statue "memory" to the beach of Moulin Blanc.

The planktonic organisms will reveal themselves to the eyes of the participants in augmented reality. Among all the species present is an intruder, can you guess which one ?

Expedition Arvik Ocean

This Sunday, April 30, will be held at the visitor's pontoon of the Moulin Blanc Marina, the departure party of the Arvik Ocean Expedition. The public will be welcomed from 2 to 5 pm.

"Whale Being" project

Cetaceans are, nowadays, more and more threatened by fishing, this expedition aims to find solution in Northern Europe.

An observation

Cetaceans are now threatened with extinction. Indeed, the number of strandings of marine mammals is clearly increasing and no concrete measures are taken to safeguard them. Approximately 400 dolphins have stranded on our coasts since December, and more than 500 000 cetaceans are victims of fishing gear every year.

The mission

The main goal of this mission is to contribute to research to understand the impacts of fishing on cetaceans and to document the actions of two NGOs (Sussex Dolphin and Whale Wise) in Northern Europe.

The sailing boat Arvik Ocean will embark the teams of the NGOs to facilitate their actions. They will exchange information to better understand the stakes and impacts of the cetacean fishing and document the actions taken. They wish to transmit their discoveries to the general public.

The routes

  • April - May : departure of the expedition, France
  • may : mission with Sussex Dolphin, England
  • July : mission with Whale Wise, Iceland
  • September : end of the expedition, return to France

The summer season is just around the corner and the desire to take to the open sea and to fully enjoy one's passion is becoming more and more pronounced! Before rushing to embark, it is necessary to prepare your boat well, because even after wintering, it needs some verifications.

Here are 6 points to check before launching:

  • Hull inspection: a simple visual check is sufficient to detect any possible problems with the hull.
  • Mooring installation, ropes and fenders: it is important to check the condition of the anchor, the chain and the different shackles. Also, the mooring lines and fenders must not be damaged.
  • Check the bilge pump: test its proper activation
  • Check the various equipment: a short inspection of all the equipment present on the boat is necessary.
  • Make sure the safety equipment is working: it's all a question of checking the expiration date.
  • Test the electronics: just turn them on and check that they are working properly.

The whole technical team is there, on site to take the boats out of the water and install them on the careening area.

Passionate people at your service!


The ifremer centre makes a call to the public to report green microalgae blooms on the Brittany coast. Indeed, this phenomen has already occurred in previous years, but never so early.


This is an evocative name for a phenomen that can be surprising when walking along the coast. It is nevertheless exceptional, occuring in spring when the sunshine and water temperature favour the growth of microalgae. This phenomen is potentially harmful for marine fauna.

The appearance of this green, red or brown water is unpredictable. Hence the importance of reporting this phenomen as soon as possible to the Ifremer scientist so that he can take a sample or call

"We encourage citizens who see coloured water to take a small quantity in a bottle and bring it to the nearest Ifremer station or relay structure as soon as possible", Anne Donner, coordinator of the Phenomer preogramme.

Yachtsmen's charter : a guide to good practices on pontoons

The Brest marinas have started the year with a new communication support aimed at annual or visiting yachtsmen : the yachtsmen's charter. Available in several forms, it aims to remind people of good practices on the pontoons and around the marina.

A few gestures to live well together

The yachtsmen's charter is available in the offices of Brest's Marinas, and is distributed to all new yahctsmen who obtain an annual contract. It reminds us of simple gestures to improve life on the pontoons and respect the environment.

Boaters will therefore find :

  • Reminders concerning noise pollution or cleanliness of the premises
  • Reminders about the safety of boats at the pontoon
  • Incentives to make good use of port structures, such as the blue stations in order to preserve the environment.

This last point is particulary important given that Brest's marinas have been awarded the Clean Ports Active in biodiversity label

A charter in several formats

Yachtsmen will discover the charter in several formats, including a map reminding them of the good practices of life in the port at the top of the gates leading to the pontoons.

Clean and Active for Biodiversity Harbours Label Renewed

After two days of auditing, the Brest Marinas have been rewarded for their work by obtaining the renewal of the Clean and Active for Biodiversity Harbours certification (Ports Propres Actifs en Biodiversité). This certification is specific to marinas and validates the actions taken to limit the impact of the harbour's activity on the environment.

Clean and Active for Biodiversity Harbours Label

This European Certification (Ports Propres Actifs en Biodiversité) specifically concerns marinas and rewards their efforts for environmental protection and sustainable development. The approach is voluntary on the part of the marinas mangers. For this to happen, certain criteria must be met such as:

  • have a trained staff who is familiar with procedures and equipment in the event of marine pollution;
  • have a careening area with a system for recovering and treating polluted water when working on the hulls of boats;
  • have a blue station for pumping out black and bilge water;
  • have waste collection points, and containers for soiled products;
  • have one or more sanitary blocks to avoid discharging grey water intor the harbour.

To date, 100 marinas have been certified as Clean Harbours, and 39, including the two marinas in Brest, have been awarded the complementary Active for Biodiversity label.

Actions carried out in Brest Marinas

Several actions are carried out in each of Brest's harbour such as :

  • participation in the "I sail, I sort" action : a programme created in 2011 which is dedicated to the prevention of marine waste and aims to develop recycling;
  • free supply of pocket ashtrays, and the installation of MéGO! ashtrays, a company that collects and recycles cigarette butts, in the vicinity of each harbour office;
  • the collaboration with Roscoff biological station, which regularly carries out checks on invasive species;
  • the installation of rainwater harversters;
  • the collaboration with Cedre, which tests the degradation and aborption of pollutants from certain waste products, and which has trained the marinas teams in oil spill response methods.

The teams of the Château Marina and Moulin Blanc Marina continue to carry out actions within the framework of this certification, and count on all the users of the marinas, from the yachtsman to the simple walker, to limit waste, discharges and protect the environment.

Fight against accidental oil pollution

Brest marinas teams regularly have to deal with small-scale pollution in the ports. To help them deal with this type of situation, Cedre provided them with two days of training in oil spill response techniques.

What is Cedre?

Located in the Moulin Blanc harbour, Cedre is an expert in accidental water pollution, from upstream preparation to the restoration of environments after accidents. It operates both in France and abroad.

Its missions are to provide expertise and advice to entities in charge of water pollution control. Cedre has also been mandated by the Ministry of Ecology to lead the network for monitoring macro- and micro-plastic waste on the coastline.

Cedre is also a training centre for professionals in the fight against accidental oil pollution. It is in this capacity that Cedre has intervened in Brest marinas.

Understanding accidental pollution in marinas

To keep the harbour clean, it is necessary to identify and understand the various possible pollutions in order to implement the right technical means.

The pollutions that we find most frequently in marinas are :

  • black and grey waters;
  • fuels;
  • natural and urban outfalls.

Faced with this, there are difficulties in managing pollution linked to the environment:

  • rip-rap, which is difficult to protect and clean;
  • pontoons, under which pollution can go;
  • boats moored to pontoons, which can end up in the middle of pollution.

The port agents, supervised by Cedre trainers, were able to test different equipments in the Moulin Blanc harbour in order to learn how to contain and clean up an oil spill. The simulation on our infrastructures allowed the team to better understand the progress of such an operation, and to identify the elements of the site that could be problematic for the deployment of the different floating booms.

Rice husks were used to simulate a fuel leak.

Cedre also has a technical platform where our teams were able to practice identifying sources of pollution, and handling the booms to contain and clean up the pollution.

What to remember about oil spill response techniques:

  • floating booms are not 100% efficient, there will always be losses;
  • diesel spreads very quickly, but evaporates in 24 to 48 hours;
  • petrol evaporates faster than diesel. However, in the event of a large leak, the area must be evacuated as there is a risk of explosion;
  • it is essential to identify the source of a spill quickly in order to be effective.

Equipments in Brest marinas to prevent pollution

The majority of pollution comes from ships moored in the port. These include ships that empty their bilges in the harbour, or those with overflowing fuel tanks.

To prevent boaters from polluting the marinas themselves, the Brest marinas provide various facilities:

  • a careening area;
  • a black water and grey water station;
  • a fuel station with retention grids;
  • a waste disposal centre with containers for soiled products;
  • a rubish dump at the top of the Moulin Blanc careening dock.

In addition, boaters will also find underground containers for household waste, cardboard and glass. Ashtrays have also been installed along the Moulin Blanc promenade and near the sanitary facilities in both harbours.

Brest marinas have been awarded the Ports Propres Actifs en biodiversité label (Clean and Active for biodiversity Harbour Label) thanks to what have been put in place to protect the environment. But to go further in the process, it is necessary for everyone to make an effort by systematically using the equipment available.
