We investigate diel variation in beaked whale diving behavior using data from time–depth recorders deployed on six Blainville’s (Mesoplodon densirostris) (255 h) and two Cuvier’s (Ziphius cavirostris) (34 h) beaked whales. Deep foraging dives (>800 m) occurred at similar rates during the day and night for Blainville’s beaked whales, and there were no significant diel differences in ascent rates, descent rates, or mean or maximum depths or durations for deep dives. Dive to mid-water depths (100… 

Diving behaviour of Cuvier's beaked whales (Ziphius cavirostris) off Cape Hatteras, North Carolina

It is found that Cuvier's beaked whales spent significantly more time near the surface at night at night than other populations of this species, but with regional differences in depth, duration and inter-dive intervals.

First Long-Term Behavioral Records from Cuvier’s Beaked Whales (Ziphius cavirostris) Reveal Record-Breaking Dives

While the previously described stereotypic pattern of deep and shallow dives was apparent, there was considerable inter- and intra-individual variability in most parameters, including significant diel behavioral variation, including increased time near the surface and decreased shallow diving at night.

Studying the Biosonar Activities of Deep Diving Odontocetes in Hawaii and Other Western Pacific Locations

Ecological acoustic recorders (EARs) have been deployed at several locations in Hawaii and in other western Pacific locations to study the foraging behavior of deep-diving odontocetes. EARs have been

Nighttime foraging by deep diving echolocating odontocetes off the Hawaiian islands of Kauai and Ni'ihau as determined by passive acoustic monitors.

Remote autonomous ecological acoustic recorders were deployed in deep waters at five locations around the island of Kauai and one in waters off Ni'ihau in the main Hawaiian island chain, detecting a variety of deep diving odontocetes, including pilot whales, Risso's dolphins, sperm whales, spinner and pan-tropical spotted dolphins, and beaked whales.

The Relationship among Oceanography, Prey Fields, and Beaked Whale Foraging Habitat in the Tongue of the Ocean

A strong correlation among increased prey density and ocean vertical structure relative to increased click densities and increased prey scattering layers is found within the Atlantic Undersea Test and Evaluation Center acoustic sensor system.

Killer whale movements on the Norwegian shelf are associated with herring density

Killer whales Orcinus orca have a cosmopolitan distribution with a broad diet ranging from fish to marine mammals. In Norway, killer whales are regularly observed feeding on overwintering Norwegian

Impacts of U.S. Navy Training Events on Blainville’s Beaked Whale (Mesoplodon densirostris) Foraging Dives in Hawaiian Waters

emphasis on the two species involved: Blainville’s (Mesoplodon densirostris) and Cuvier’s (Ziphius Blainville’s beaked whales (Mesoplodon densicavirostris) beaked whales (England et al., 2001).

Changes in spatial and temporal distribution and vocal behavior of Blainville's beaked whales (Mesoplodon densirostris) during multiship exercises with mid‐frequency sonar

The number and distribution of vocalizing groups of Blainville's beaked whales were analyzed before, during, and after multiship mid-frequency active sonar operations at the US Navy's Atlantic Undersea Test and Evaluation Center (AUTEC) in the Bahamas.

First direct measurements of behavioural responses by Cuvier's beaked whales to mid-frequency active sonar

The first direct measurements of behavioural responses of this species to mid-frequency active (MFA) sonar signals are obtained, with responses to playback well below current regulatory thresholds; equivalent responses to operational sonars could elevate stranding risk and reduce foraging efficiency.

Extreme diving of beaked whales

Using current models of breath-hold diving, it is inferred that beaked whales' natural diving behaviour is inconsistent with known problems of acute nitrogen supersaturation and embolism, and possible decompression problems are more likely to result from an abnormal behavioural response to sonar.

Diving and foraging behavior of leatherback sea turtles (Dermochelys coriacea)

Remote time–depth recorders were deployed on six gravid leatherbacks nesting on Sandy Point, St Croix, and distinct diel periodicity was observed in dive behavior; submergence intervals were longest at dawn, declined throughout the day, and were shortest at dusk.

Using suction–cup attached time–depth recorder/VHF radio tags, the first diving data is obtained on northern bottlenose whales (Hyperoodon ampullatus), the first such data on any species within the family Ziphiidae, suggesting that these whales may make greater use of deep portions of the water column than any other mammal so far studied.

Diving behaviour of Cuvier's (Ziphius cavirostris) and Blainville's (Mesoplodon densirostris) beaked whales in Hawai'i

Diving behaviour of Cuvier's and Blainville's beaked whales was studied using suction-cup-attached time-depth recorders, and both species appeared to prepare for long dives by spending extended periods of time near the surface.

The results, together with the series of deep dives recorded immediately after sunset, suggest that pantropical spotted dolphins around Hawaii feed primarily at night on organisms associated with the deep-scattering layer as it rises up to the surface after dark.

Fur seal diving behaviour in relation to vertical distribution of krill

It is suggested that because krill migrate vertically fur seals are able to exploit them most efficiently during shallow dives at night, which is consistent with previous studies of predator-prey interactions.

The data suggest that Hawaiian tiger sharks move within large home ranges and that they can efficiently navigate between distant parts of their range, even when this requires crossing open ocean waters.
