It was a thrilling hour of high-energy diving.
The bird could on average dive up to 75 m for its prey with the maximum dive depth being estimated at 130 m; however, to conserve energy, most dives were shallower.
This may also explain observations of polar bears expending energy to dive, then selectively eating only specific parts of marine algae plants (C.J. Jonkel pers. comm., [ 14, 57, 58]).
The Office for National Statistics said output in the energy supply sector dived by 5.4% month-to-month, accounting for 0.5 percentage points of the fall in overall production, as demand for heating energy from households and businesses was lower than usual owing to the mild winter in much of the country.
The whales use about 63,000 kilojoules of energy on each dive, the researchers report online today in The Journal of Experimental Biology.
The afternoon filled the space with a rush of fresh energy as guests dove into their beautifully busy event appointments.
In eco-physiological modeling of diving energetics it is often useful to convert mechanical energy spent during a dive to a more biological currency of energy such as metabolic rate (often measured as the amount of oxygen consumed by the duck).
He soon found a peculiar niche: dirtying up the Western canon with the louche energy of an East Village dive bar.
We consider, therefore, that the uniquely thin and extended construction of the amphitheatre, has relevance as an energy absorptive structure in diving.
They also use glycolysis metabolism to compensate for insufficient levels of oxygen (Butler and Jones 1997), which potentially supports the energy supply for their long dives.
Plunge diving allows birds to use the energy from the momentum of the dive to combat natural buoyancy (caused by air trapped in plumage), and thus uses less energy than the dedicated pursuit divers, allowing them to utilise more widely distributed food resources, for example, in impoverished tropical seas.
