The occurrence of humpback whales across the Hawaiian archipelago revealed by fixed and mobile acoustic monitoring

open access: yesFrontiers in Marine Science, 2023
The occurrence of humpback whales (Megaptera novaeangliae) across the 2600 km of Hawaiian archipelago, which include the remote atolls, banks, and seamounts of Papahānaumokuākea Marine National Monument (PMNM), remains poorly understood. Previous surveys

Research on the characteristics of wave observation of wave glider

open access: yesJournal of Physics: Conference Series, 2020
Abstract Wave glider is a new class of ocean mobile observation vehicle. It is a new applied research direction that using wave glider for wave observation. Currently, wave observation is usually performed at fixed points by using wave buoys, the research on using wave glider for navigational observations is still rare, and the ...

Further evidence of humpback whale presence in deep tropical ocean during the breeding season: confirmation and extension of acoustic detections between Hawaii and Mexico

open access: yesFrontiers in Marine Science, 2023
During winter humpback whales converge on tropical breeding grounds characterized by shallow, warm seas. In the eastern half of the North Pacific two such breeding grounds are located along the shorelines and shallows of Mexico, and in mid-ocean around ...

The surface diurnal warm layer in the Indian Ocean during CINDY/DYNAMO [PDF]

open access: yes, 2014
A surface diurnal warm layer is diagnosed from Seaglider observations, and develops on half the days in the CINDY/DYNAMO Indian Ocean experiment. The diurnal warm layer occurs on days of high solar radiation flux (>80 W m-2) and low wind speed (
