Better Underwater Propulsion: 5 kicks to improve your diving
To a new diver, propulsion is achieved by any means necessary. The use of legs, arms, hands, large marine animals, currents and other divers are all useful elements in completing the journey from Sponge A to Coral Head B. In defense of the new diver, rarely is propulsion explained let alone practiced in a basic or advanced scuba class. A new diver might be told to kick from the hip, point their toes, don’t bend the knees, don’t bicycle kick, etc. To a new diver propulsion means wiggling your feet until you get to the other side of the pool and if that is too difficult you can buy a different pair of fins that will be easier on the legs. For DIR education, proper propulsion techniques are an essential part. After a diver develops a solid base of buoyancy control along with body mechanics and trim, different propulsion techniques are added [...]
Sea Turtles In Crisis
PUT SEA TURTLE FLYING OVER SANTA ROSA WALL HERE All sea turtle species (green, hawksbill, Kemp’s ridley, leatherback, loggerghead, and olive ridley) are officially classified as either “threatened” or “endangered.” They are in trouble for many reasons. One is natural predators: Turtles are menu favorites for tiger sharks, and hatchlings are devoured by sea-birds as they scamper across the beach seeking safety in the waves. But their most significant threat is from earth’s number one apex predator: humans. Coastal development destroys nesting and foraging habitats. Shore lighting confuses turtles’ navigation ability, since they rely on moonlight and starlight. Commercial fishing gear (gillnets, baited long-lines, trawl nets, etc.), kill thousands of turtles every year as wasted “bycatch.” Finally, tens of thousands are taken directly by humans annually for eggs, meat, and decorative jewelry.
