Sarung tangan adalah salah satu peralatan menyelam yang paling sering diabaikan dan bersifat individual. Saat memilih sarung tangan, pertimbangkan jenis penyelaman yang Anda rencanakan dan apa yang Anda harapkan dari pelindung tangan Anda. Saat memilih sarung tangan, pertimbangkan faktor-faktor berikut: perlindungan termal, kesesuaian, ketangkasan, perlindungan dari bahaya, ketahanan terhadap benturan, dan bahan.
Reduced exercise tolerance is common for those with chronic obstructive pulmonary disease and poses risks for diving. There can be strenuous activity involved with managing currents, swimming on the surface in choppy seas or pulling yourself and your heavy gear up a ladder and onto an unsteady boat. With COPD, shortness of breath during exertion doesn’t mean you are out of shape; it means you cannot rid your body of carbon dioxide and replace it with the oxygen needed to meet the demand of your exertion.
Interactions between different species, whether above or below water, typically revolve around confrontations between predators and prey. At the opposite and more harmonious end of the spectrum, a scattering of unrelated species coevolved to form lifelong alliances for their mutual security. These relatively rare go-along-to-get-along partnerships provide a net benefit for both parties, improving each species’ reproductive success. The close living arrangement between weak-eyed alpheid snapping shrimp and sharp-eyed partner gobies is a classic example of symbiosis in the sea.
Sometimes life gets in the way — family obligations, unforeseen injuries, work responsibilities, social events — or perhaps the world as we know it shuts down for a while. When these things overwhelm us, many people tend to sacrifice exercise first. You may miss a few workouts, and then your exercise routine slowly slips from regular to nonexistent. It happens to most people — even fitness experts and professional athletes — at some time. Although it may feel challenging, it is possible to restart your exercise routine.
Michael Aw’s early life while growing up in Singapore — he didn’t see the ocean until age 17 — gave few clues that he would one day become one of the most influential print journalists in destination diving and ocean conservation. The author of or major contributor to 43 books, Aw created Ocean Geographic magazine in 2007 and also leads expeditions, often to exotic regions. He now hopes to raise awareness of the folly of shark-finning and the overexploitation of our marine resources.
Kisah pencarian kapal selam Jepang I-52 adalah salah satu dari dua penemuan yang dipisahkan oleh waktu dan tujuan. Dalam kegelapan malam di Samudra Atlantik pada tahun 1944, kapal anti-kapal selam Angkatan Laut AS mencari pertemuan rahasia antara kru angkatan laut Jerman dan Jepang. Beroperasi berdasarkan informasi intelijen yang diperoleh, mereka berusaha mengejutkan dan menenggelamkan kedua kapal selam tersebut. Setengah abad kemudian, I-52 masih belum ditemukan di dasar laut, tetapi kali ini pencarian dilakukan dalam kegelapan lautan dalam untuk mengejar kemungkinan, bukan kehancuran.
Pada Musim Gugur 2013, istri saya, Liv, dan saya mengawasi 16 penyelam baru yang mengalami jarak pandang rendah untuk pertama kalinya. Tempat pelatihan kami memiliki kedalaman maksimum [...]
A diver didn’t heed the divemaster’s warning and was lost at sea. Deploying his large surface marker buoy helped with his rescue. DAN recommends that divers always listen to the dive briefing and follow all directions and always carry an SMB and reel. If your breathing-gas supply is critically low, get to the surface at a safe ascent rate, and then monitor for signs of decompression illness. It is better to deal with DCI on the surface than to run out of breathing gas at depth.
Located in the Bay Islands of Honduras, Roatán is a tropical gem nestled in the turquoise waters of the Caribbean Sea. The largest of the Bay Islands, Roatán sits about 30 miles off the Honduran coast between Utila and Guanaja. Its fringing reef system makes up the southernmost edge of the Mesoamerica Reef (the world’s second-largest reef system) and is arguably Roatán’s biggest attraction.
