Jakarta \u2014 Swimming in a giant aquarium filled with thousands of fish\nrepresents a rare experience for most people. However, for Chandra (35),\na diver at SeaWorld Ancol in North Jakarta, this activity is part of his\ndaily routine.<\/p>\n
Over the past seven years, Chandra has worked diving in the SeaWorld\naquarium, which is home to approximately 175 species of marine life,\ntotalling around 8,000 fish. He does not merely observe the marine biota\nfrom behind aquarium glass, but swims directly amongst thousands of\nfish.<\/p>\n
Despite spending each day in the aquarium\u2019s artificial seawater,\nChandra reports that his skin and body remain healthy. \u201cIt never itches,\nbecause the water here at SeaWorld is better. This is genuine seawater\nthat we take from Ancol, but the process to get it here is lengthy,\u201d\nChandra said during an interview at the location on Tuesday (10 March\n2026).<\/p>\n
Seawater used in the aquarium is not simply placed inside. It must\nundergo a lengthy series of processes, including ozonisation,\nfiltration, and several other purification stages. Through these\nprocesses, seawater entering the aquarium is ensured to be free of\ncontaminants and bacteria, making it clearer and safer for both marine\nlife and divers.<\/p>\n
Water quality is important because the aquarium is inhabited not only\nby thousands of fish, but also serves as a workplace for divers who must\nremain in the water for set periods.<\/p>\n
Nevertheless, Chandra recognises that his work carries significant\nrisk if not performed carefully. One health risk that divers can\nexperience is decompression sickness, a condition when nitrogen in the\nblood or body tissues forms bubbles due to sudden pressure changes.<\/p>\n
\u201cIf decompression occurs it is very dangerous and can cause death,\nthe lungs can rupture, the eardrum can burst,\u201d he said.<\/p>\n
However, this does not necessarily mean absolute safety for health.\nBacteria cannot be entirely eliminated, because an aquarium is a living\necosystem and fish, fish food, and biofilters continually produce\nmicroorganisms.<\/p>\n
Some types of bacteria can still be found in aquarium systems,\nincluding Mycobacterium marinum, which can cause skin infections in\npeople who frequently contact aquarium water.<\/p>\n
Decompression sickness (DCS) is indeed one of the frequent health\nrisks faced by divers. Decompression is a medical condition when gas\nbubbles, particularly nitrogen, form in the blood and body tissues due\nto pressure changes that occur too rapidly. This condition typically\noccurs when a diver ascends to the surface too quickly after diving for\nan extended period.<\/p>\n
When a diver is in water, pressure on the body increases as depth\nincreases. Pressure underwater increases approximately one atmosphere\nfor every ten metres of seawater depth. The deeper and longer a person\ndives, the more nitrogen is absorbed by the blood, muscles, fatty\ntissues, and joints.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/diving-profession-involves-more-than-attraction-risks-include-ear-injury-and-death-1773248065", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
