Inverse Echo Sounding: Using measured water depth to calculate water temperature and its variation over time
Inverse echo sounding is a new method that, in this investigation, has been used to calculate average temperature difference in the water column over time using the difference in the recorded depth of points on the sea floor. The study took place over Cross Seamount, an inactive seamount, 300km southwest of the Islands of ...
The Abundance and Distribution of Small Zooplankton near Cross Seamount
Seamounts are isolated shallow regions of the oceans formed by volcanoes. Seamounts have been found to support unusually large numbers of fish. It is possible that fish on seamounts are feed on small animals called zooplankton that drift over seamounts with the currents. In most of the surface ocean, fish hunt using their ...
Zooplankton diel vertical migration and distribution relative to Cross Seamount using 75 kHz acoustic and net tow surveys
This project attempts to quantify and explain differences in zooplankton distribution and abundance on the top and sides of Cross Seamount, Hawaii. Zooplankton were collected with nets at different depths during both day and night tows. Properties of the water column (temperature, salinity, and chlorophyll content) were also ...
Seafloor terrain and sediment characterization at Molokaʻi, Lōʻihi, and Cross Seamount via seafloor mapping
Research conducted between 27 Dec. 2010–4 Jan 2011 in Hawaii, at Molokai, Loihi, and Cross Seamount, combined seafloor mapping with sediment analysis to provide a comparison of different sediments over different terrain characteristics. The sediments from the sampling locations were dominated by a range of sediments, from ...
Internal tides at Cross Seamount
The R.V. Thomas G. Thompson was used to study currents in the North Pacific Ocean over Cross Seamount, a large extinct submarine volcano South of Oahu, Hawai’i. An Acoustic Doppler Current Profiler (ADCP) was used to measure currents over the seamount. A mathematical model for the tide was created using the data collected by ...
