No clear diel patterns in dive depth were apparent, although diving depths appear to have been greatest in mid morning and again before sunset, which shows partial overlap with deeper diving periods for sooty shearwaters [11].
On the other, depth of last foot-stroke may depend on maximum dive depth, assuming birds load more air when diving deeper, therefore longer.
In our study, we examined the factors that affect the swim speed of diving seals while manipulating three conditions (drag, buoyancy, and dive depth) and showed that only drag affected swim speed, which agreed with a previous theoretical prediction (Sato et al., 2010).
The maximum recorded dive depth is 274 metres (900 feet).
Their maximum dive depth is 370 metres (1,200 feet), and they may stay underwater for only 16 minutes before resurfacing.
The interface for entering dive data is intuitive — twirling dials to set dive depth, for example, or choosing from a prepopulated list of dive types (like "fun" or "wreck").
In order to make a quick assessment of the seriousness of the dive accident, a good patient history should then be taken concerning dive depth, duration and whether there has been done any safety or decompression stops during ascent.
As a general rule, dive depth and duration tend to scale with body size and body mass - but Cuvier's (adults around 2,500kg) are much smaller than other deep-diving species like sperm whales (up to 57,000kg).
This extensive investigation permitted the first comprehensive study of the at-sea ecology of yelkouan shearwaters showing strikingly coastal habits, partial migration, unsuspected diving capabilities (max dive depth of 30 m), and a broad diet ranging from zooplankton to small pelagic fish.
The "must-have accessory for the connected scuba diver" started out simply measuring dive depth and water temperature, but DiveNav has added many more measurements in its dive analyzer, including ascent rate, tank pressure profile, dive time remaining and CNS clock if you dive Nitrox (and if you have to ask, you don't).
They went down to a maximum dive depth of 195 meters (640 feet).
