Abstract:

This dataset contains the input python scripts and the output data for a simulation of fate and transport of natural gas seep bubbles during the Gulf Integrated Spill Research (GISR) G08 cruise at Mississippi Canyon, lease block 118 (MC118) using the Texas A&M Oilspill Calculator (TAMOC). The GISR G08 cruise was conducted from 2015-04-09 to 2015-04-21 in the northern Gulf of Mexico on the E/V Nautilus cruise NA056 using the remotely operated vehicle (ROV) Hercules. A total of five simulations were conducted for five individual ROV dives. For one dive, diffusivity was varied. Model results include bubble time, bubble diameter, position, slip velocity, and density. Other related datasets are also available at GRIIDC under different Unique Dataset Identifiers (UDIs): R1.x137.000:0026 (DOI: 10.7266/N79K48TN; transport of bubbles with isotopic ratio calculations), R1.x137.130:0016 (DOI: 10.7266/N7GF0RF5; stereoscopic high-speed imagery of seeps), and R1.x137.130:0017 (DOI: 10.7266/N79C6VB3; ROV video imagery of seeps at the site).

Purpose:

To understand the fate and transport of bubbles from natural gas seep from the deepwater environment, i.e., from the sources below the hydrate stability line.

Data Parameters and Units:

Time [s], bubble diameter [m], X coordinate [m], Y coordinate [m], Z coordinate [m], bubble slip velocity [m/s], bubble density [kg/m^3].

Methods:

The single bubble model module of the Texas A&M Oilspill Calculator (TAMOC) was used to simulate the behavior of rising seep bubbles. Initial conditions and currents were drawn from five remotely operated vehicle (ROV) dives on the Gulf Integrated Spill Research (GISR) G08 cruise. The model predicts the trajectory of one thousand bubbles per dive, drawn from an initial log-normal size distribution. Further details can be found in the associated publication Wang et al., (2020).
