Navigation zones<\/h1>\n

Depending on the day's weather, we decide on one of the 3 navigation zones, the wind and swell being the determining factors. The fish on which the dolphins we observe feed follow the wind and current.<\/p>\n

Dolphins don't like to face wind and waves, so they'll do what the fish they're chasing do: take cover.<\/p>\n

There are 3 areas on Cap de Creus where we can go, so we'll choose the one most protected from the wind and waves.<\/p>\n

    \n
  • Zone 1\u00a0 <\/span><\/b>Situated on the Cap de Creus canyon, it's the perfect choice if there's no wind or waves. The canyon descends to a depth of 2,000 meters (around the canyon, the average depth is only 150 meters). It's a very rich ecosystem, with all the marine flora and fauna living there sheltered from the strong underwater currents because they're protected in the depths.<\/li>\n
  • Zone 2<\/b> \u00a0 <\/span>Located to the north of Cap de Creus, it stretches from the cape to Port de la Selva. This area is ideal for sailing in strong southerly winds, as it is protected by the cape. A circular current is created, and surface fish such as sardines and mackerel, which cetaceans love, find their way here, making this area a hunting ground for dolphins.<\/li>\n
  • Zone 3\u00a0 <\/b>Located to the south of Cap de Creus, it stretches from the cape to Roses. This area is ideal for sailing in strong northerly winds, such as the Tramontane, as the sailing area is protected by the cape. A circular current is created, and surface fish such as sardines and mackerel, which cetaceans love, find their way here, making this area a hunting ground for dolphins.<\/li>\n<\/ul> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Cetaceans living in our research area<\/h1>\n

    Here is a brief presentation of the animals we observe in our research territory.\u00a0\u00a0<\/span>If you'd like to find out more about these three species, we strongly recommend you take a look at the Internet, where you'll find a wealth of fascinating information to help you prepare for your outing.<\/span><\/p>\n

    How to spot them from the boat:<\/span><\/h3>\n

    Their dorsal fin, as well as the splashes they produce when swimming and jumping, help to pinpoint their position.\u00a0As soon as you think you've spotted them, tell the captain, he'll check, but then remain silent ... shhh ...<\/span><\/p>\n

    We have 3 species of year-round resident dolphins in our research area: thee Tursiops truncatus<\/span> or Bottlenose dolphin<\/span>, the Stenella coeruleoalba<\/span> or Blue and white dolphin<\/span> and the Delphinus delphis<\/span> or Short-beaked common dolphin<\/span>.<\/span><\/p>\n

    \u00a0<\/h3>\n

    1 - Tursiops truncatus\u00a0<\/span>or Bottlenose dolphin:<\/h3>\n

    Bottlenose dolphins generally measure 2 to 4 meters in length, and weigh 150 to 400 kilograms.<\/p>\n

    Color: Various shades of gray on the back, and white on the belly. On the sides, the gray is paler. This coloring provides a camouflage effect.<\/p>\n

    Location, it's an \u00abinshore\u00bb dolphin, he'll sleep close to the coast at night, but during the day we find him hunting in our 3 zones.<\/p> <\/div>\n<\/div>\n\n

    \n
    \n \"Dauhpin \n <\/div>\n \n \n <\/div>\n\n
    \n
    \n

    2 - The Stenella coeruleoalba or Blue and White Dolphin<\/h3>\n

    Blue and white dolphins generally measure between 1.90 m and 2.60 m for 80 to 150 kg.<\/p>\n

    Color: Sickle-shaped dorsal fin, fairly dark back, gray, white and blue flanks. This dolphin has about three blue stripes starting from the eye, a small notch on the caudal fin, and one or two blue stripes running from the flank to the dorsal fin.<\/p>\n

    Location: a pelagic dolphin, it lives offshore in the canyon, about 6 nautical miles (10 km) from the coast, but can come close to shore to hunt.<\/p> <\/div>\n<\/div>\n\n

    \n

    \n
    \n

    3 - Delphinus delphis or Short-beaked common dolphin<\/h3>\n

    Size: from 180 to 260 cm with a mass varying from 75 to 115 kg<\/p>\n

    Color :<\/strong>\u00a0The back is bluish-gray to black. The flanks feature two large light spots (buff for the front spot and light gray for the rear) that meet at a point just below the dorsal fin.<\/span><\/p>\n

    Location<\/strong> Blue and white: also pelagic, it lives offshore in the canyon, but like the blue and white, it can come close to shore to hunt.<\/p> <\/div>\n<\/div>\n\n

    Les zones de navigation<\/h1>

    Nous d\u00e9cidons suivant la m\u00e9t\u00e9o du jour d\u2019une des 3 zones de navigation, le vent et la houle sont d\u00e9terminants. Les poissons dont se nourrissent les dauphins que nous observons suivent le vent et le courant.<\/p>

    Les dauphins n\u2019aiment pas affronter le vent et les vagues donc ils vont faire comme les poissons qu\u2019ils chassent, se mettre \u00e0 l\u2019abri.<\/p>

    Il existe 3 zones au Cap de Creus o\u00f9 nous pouvons nous rendre, nous choisirons la zone la plus prot\u00e9g\u00e9e du vent et des vagues.<\/p>

    • La zone 1\u00a0 <\/b>Situ\u00e9e sur le canyon du Cap de Creus, elle sera choisie si il n\u2019y a pas de vent et de vagues, le canyon descend jusque\u2019\u00e0 2000 m\u00e8tres de profondeur ( autour du canyon, la profondeur moyenne n\u2019est que de 150 m\u00e8tres ) C\u2019est un \u00e9cosyst\u00e8me tr\u00e8s riche, nous y trouvons toute la flore et la faune marine qui y vit \u00e0 l\u2019abri des forts courants sous marins car ils y sont prot\u00e9g\u00e9s dans les profondeurs, cet eco syst\u00e8me est nourri par les alluvions qui transportent les oligo \u00e9l\u00e9ments n\u00e9cessaires depuis les fleuves et rivi\u00e8res voisines.<\/li>
    • La Zone 2<\/b> \u00a0 Situ\u00e9e au nord du Cap de Creus, elle part du cap et s\u2019\u00e9tend jusqu\u2019\u00e0 Port de la Selva, cette zone sera privil\u00e9gi\u00e9e lors de fort vent du sud, car la zone de navigation y est prot\u00e9g\u00e9e par le Cap. Un courant circulaire s\u2019y cr\u00e9e alors et les poissons de surface, sardines ou maquereaux, dont sont friands les c\u00e9tac\u00e9s, s\u2019y retrouve et cette zone devient alors un territoire de chasse pour les dauphins.<\/li>
    • La Zone 3\u00a0 <\/b>Situ\u00e9e au sud du Cap de Creus, elle part du cap et s\u2019\u00e9tend jusqu\u2019\u00e0 Roses cette zone sera privil\u00e9gi\u00e9e lors de fort vent du nord, comme la Tramontane, car la zone de navigation y est prot\u00e9g\u00e9e par le Cap. Un courant circulaire s\u2019y cr\u00e9e alors et les poissons de surface, sardines ou maquereaux, dont sont friands les c\u00e9tac\u00e9s, s\u2019y retrouve et cette zone devient alors un territoire de chasse pour les dauphins.<\/li> <\/ul>\n\"Les\n

      Les c\u00e9tac\u00e9s qui vivent sur notre zone de recherche<\/h1>

      Voici une br\u00e8ve pr\u00e9sentation des animaux que nous observons dans notre territoire de recherche.\u00a0\u00a0Si vous voulez plus de renseignements sur ces trois esp\u00e8ces, nous vous conseillons vivement de parcourir le net ou des milliers d\u2019informations diverses et passionnantes vous permettrons de bien pr\u00e9parer votre sortie.<\/p>

      Comment les rep\u00e9rer depuis le bateau :<\/h3>

      Leur nageoire dorsale, ainsi que les \u00e9claboussures qu'ils produisent lorsqu'ils nagent et qu'il sautent, permettent de rep\u00e9rer leur position.\u00a0D\u00e9s que vous avez l\u2019impression de les avoir rep\u00e9r\u00e9s, dites le au capitane, il va v\u00e9rifier, mais ensuite restez en silence \u2026 chut \u2026<\/p>

      Nous avons 3 esp\u00e8ces de dauphins r\u00e9sidents \u00e0 l\u2019ann\u00e9e sur notre territoire de recherche : le Tursiops truncatus ou Grand dauphin, le Stenella coeruleoalba ou Dauphin bleu et blanc et le Delphinus delphis ou Dauphin commun \u00e0 bec court.<\/p>

      \u00a0<\/h3>

      1 - le Tursiops truncatus\u00a0ou Grand dauphin :<\/h3>

      Les grands dauphins mesurent g\u00e9n\u00e9ralement de 2 \u00e0 4 m\u00e8tres de longueur, pour un poids\u00a0: de 150 \u00e0 400 kilogrammes.<\/p>

      Couleur : Diverses teintes de gris sur le dos, et blanc sur le ventre. Sur les c\u00f4t\u00e9s, le gris est plus p\u00e2le. Cette coloration procure un effet de camouflage.<\/p>

      Localisation, c\u2019est un dauphin \u00ab\u00a0c\u00f4tier\u00a0\u00bb il ira dormir le soir pr\u00e9s des c\u00f4tes, mais la journ\u00e9e nous le trouvons entrain de chasser sur nous 3 zones.<\/p>\n\"Dauhpin\n

      2 - Le Stenella coeruleoalba ou Dauphin bleu et blanc<\/h3>

      Les dauphins bleus et blancs mesurent g\u00e9n\u00e9ralement entre 1,90\u00a0m \u00e0 2,60\u00a0m pour 80 \u00e0 150\u00a0kg.<\/p>

      Couleur : La nageoire dorsale est en forme de faucille, le dos assez sombre, les flancs gris, blancs et bleus. Ce dauphin pr\u00e9sente environ trois bandes bleues partant de l'\u0153il, une petite entaille sur la nageoire caudale, et une ou deux bandes bleues qui courent du flanc \u00e0 la nageoire dorsale.<\/p>

      Localisation, c\u2019est un dauphins p\u00e9lagique, il vit au large sur le canyon \u00e0 environ 6 miles nautiques ( 10 km ) de la cote, mais peut s\u2019approcher des c\u00f4tes pour chasser.<\/p>\n\"dauphin-bleu-blanc-1.jpg\"\n

      3 - Le Delphinus delphis ou Dauphin commun a bec court<\/h3>

      Taille : de 180 \u00e0 260 cm avec une masse variant de 75 \u00e0 115 kg<\/p>

      Couleur :<\/strong>\u00a0son dos est d'une teinte allant du gris bleut\u00e9 au noir. Les flancs pr\u00e9sentent deux grandes taches claires (chamois pour la tache avant et gris clair pour l'arri\u00e8re) se rejoignant en un point situ\u00e9 \u00e0 l'aplomb de la dorsale.<\/p>

      Localisation<\/strong> : il est \u00e9galement p\u00e9lagique et vit au large sur le canyon, mais comme le bleu et blanc, il peut se rapprocher des c\u00f4tes pour chasser.<\/p>\n\"dauphin-bleu-blanc-1.jpg\"\n

      Voil\u00e0 pour les principaux animaux r\u00e9sident que nous observons mais si nous avons de la chance nous pouvons admirer une baleine dite rorqual commun.<\/h5>
      Bonne observation et surtout n\u2019oubliez pas de garder le silence sur le bateau...<\/h5>","_links":{"self":[{"href":"https:\/\/www.shelltonewhaleproject.org\/en\/wp-json\/wp\/v2\/pages\/3680","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.shelltonewhaleproject.org\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.shelltonewhaleproject.org\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.shelltonewhaleproject.org\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.shelltonewhaleproject.org\/en\/wp-json\/wp\/v2\/comments?post=3680"}],"version-history":[{"count":0,"href":"https:\/\/www.shelltonewhaleproject.org\/en\/wp-json\/wp\/v2\/pages\/3680\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.shelltonewhaleproject.org\/en\/wp-json\/wp\/v2\/media?parent=3680"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
