Harned, Doug and Richard - Science in Focus (with Bells), detail 1, 2015, AGU climate film compilation. A very different goal than building a website, but the principle is the same.
Competitive swimmers execute headfirst dive entries from starting blocks into pools where water depths can vary. While it has been a worrisome trend in Australia for a while — due to the coast and snorkeling adventures — it may be a worry you've never heard about. And I don't want them to misjudge when it becomes dangerous to jump into shallower water. However, in areas where the water is very deep, it takes the water additional energy to heat up. Motivation to swim in deeper water can come from a desire to overcome fear, the urge to explore a new environment or try something new, or simply because swimming in deeper water allows for better swimming performance. "We generally have to add light to the scene to create contrast or bring out color, but if we stay shallow or have very clear water, then the sunlight is all we need. If you've ever gone swimming, you probably know the pain and suffering of a dive gone wrong. Both Molasses Reef and French Reef have great drift dive sites. Shallow reefs, mangroves and seagrass beds all function as important nurseries, where juvenile fish are protected from larger predators. Because Shallow Water Blackout occurs with no warning, the result is almost always fatal when the victim is in the water.
