A time series of six sonar images collected over gaseous seeps at Biloxi Dome. The yellow-green vertical columns are seeps of gas bubbles emitted from the seafloor (red). Note changes in seep intensity through time and the appearance of "bursting" behavior denoted by the arrows.

A gas capture device, called the methane bucket, was assembled and deployed on the Little Hercules. The methane bucket allows for estimating the volumetric flow rate associated with bubbles of methane gas at natural seeps. The methane forms a mix of hydrate (methane ice) and gas at depth but when brought to the surface the hydrate dissociates allowing measuring gas volume.

Three bubbles of less dense than water hydrocarbon gas and fluids escaping from an oil, gas, and brine seep area. The left-most bubbles seem to have escaping material that is leaving a trail of the bubble trajectories through the water column.

Small mounds or volcanoes around the periphery of a brine pool rose small heights (centimeters) from the seafloor. Some of these small volcanoes were emitting gas, probably also mixed with liquid hydrocarbons and brine. Is the brown material covering the black oil a mineral precipitate or is it of biological origin?

A small "volcano" around the periphery of a brine pool rose small heights (centimeters) from the seafloor. Some of these small volcanoes were emitting gas, probably also mixed with liquid hydrocarbons and brine. Note the bubble of gas rising from the small volcano reflecting the lights of Little Hercules giving an illusion of eyes staring back at the camera.

An aggregation of vestimentiferan tubeworms (Lamellibrachia sp.). Such aggregations provide habitat for smaller animals such as the small white anemones covering the tube worm tubes, and the shrimps Alvinocaris muricola. The tiny white spots all around the tubeworms are copepods, tiny swimming crustaceans.

First map of an oceanic basin. Matthew Fontaine Maury produced this map in 1853 and published it in the Wind and Current Charts for that year.
6894 thumbnail picture
Second map of an oceanic basin. Matthew Fontaine Maury produced this map in 1854 and published it in the Wind and Current Charts for that year. This map had significantly more data than the 1853 map including soundings by Lt. Otway Berryman, USN, on the USS DOLPHIN over the Mid-Atlantic Ridge (MAR) north of the Azores. These were the first soundings on the MAR.

Bottom characteristic map of the approaches to New York Harbor by "United States Hydrographical Office" as published in Matthew Fontaine Maury's Wind and Current Charts for 1858. Data from United States Coast Survey. Note there is no expression of Hudson Canyon below the continental shelf break although the channel of the Ice Age Hudson River is clearly shown.

First profile of an oceanic basin. Matthew Fontaine Maury produced this profile in 1854 and published it in the Wind and Current Charts for that year.

An early example of a microscopic examination of ocean bottom sediment. This was published with a report by Lt. Joseph Dayman, RN, who ran a line of sounding s across the Atlantic Ocean from Newfoundland to Ireland on HMS CYCLOPS in 1857. This was the second line run and covered the same ground sounded by Lt. Otway Berryman for the USCS on the ARCTIC in 1856.

Sounding on the HMS CYCLOPS in mid-Atlantic Ocean in August 1857. The diagram on the right shows the problem with early hemp sounding line methods. The line would keep running out after reaching bottom and the surveyors would not be able to ascertain an accurate depth.
6899 thumbnail picture
Top panel same as image map00006. Bottom panel demonstrates method of detaching weight and retrieving bottom sample such that the surveyor would at least know that the sounding weight had reached bottom. However, this did not improve the accuracy of the sounding.
