2024-Present Jackpile-Paguate Uranium Mine Superfund Site Uranium Transport Review, Source Assessment and Modelling

SCLLC is contracted by Woodward & Curran to review transport and fate for mine sourced uranium relative to natural background values at the Jackpile-Paguate Uranium Mine Superfund Site (JPUMSS).  Investigation applies comparison uranium concentration, speciation, isotope ratios.  This isotope analysis will determine a source contribution to complex mixtures of the same element in different geologic formations and is a function changes in the geologic source and… Read more »

BIL – Carbon Offshore Storage in Mustang Island Corpus Christi (Project CO2SMICC)

Drs. Coffin and Abdulla will be working on the CO2SMICC project contracted through Texas A&M University – Corpus Christi (TAMU-CC) and this project is organized with Repsol for offshore CO2 storage. Oversight for this project is conducted by Southern States Energy Board.  TAMU-CC and SCLLC is responsible for monitoring and environmental health impact and prediction of long term CO2 storage.  This project is supported by DOE – NETL….

New Zealand Drilling Planning

Dr. Coffin co-lead with Dr. Pecher (Texas A&M University _Corpus Christi) and Dr. Lowell Stott (University of Southern California) to organize an International Ocean Discovery Plan (IODP) research expedition on the Chatham Rise off of the Eastern Coast of New Zealand, where we observed methane gas hydrate instability and gas escape that coincided with raised temperature and lowered pressure. During June and July 2020 Dr. Pecher… Read more »

2020 – 2021 Hackensack River Coffin and Provectus

Dr. Coffin is working with Provectus Environmental Products to apply isotope geochemical analysis of polyaromatic hydrocarbons (PAH) to confirm statements from the New Jersey Environmental Protection Agency about a company’s contribution to New Jersey Hackensack River contamination.

2022 to present Victoria Texas Oil Refining Via Acoustic Harmony And Select Frequencies

Drs. Abdulla and Coffin are working with Total Machining Solutions on applying harmonic frequency cascade (HFC) to oil refining and desulfurization. HFC provides capability to refine oil to different petroleum stocks and remove sulfur in oil. This novel work provides technical, environmental, and financial benefits such as: • Environmental reductions in carbon, nitrogen, and sulfur gas emissions, • Portable fuel refining capability available to remote locations… Read more »

A REVIEW ANALYSIS OF GAS HYDRATE TESTS: ENGINEERING PROGRESS AND POLICY TREND.

Environmental Geotechnics Chen, L. Merey, S., Pecher, I. Okajima, J. Komya, A., Diaz-Naveas, J., Li, S., Maruyama, S., Kalachand, S. Kvamme, B., Coffin, R. Methane hydrate has become one promising energy resource for humankind. In this study, recent worldwide onshore/offshore drilling and production activities are analyzed. The most recent reports from sites such as Japan (2013 and 2017) and China (2017) show that the road towards… Read more »

DISSOLVED INORGANIC CARBON PUMP IN METHANE-CHARGED SHALLOW MARINE SEDIMENTS: STATE OF THE ART AND NEW MODEL PERSPECTIVES.

Frontiers in Marine Science. Akam, S.A., Coffin, R.B., Abdulla, H.A., Lyons, T.A. Our data synthesis and broad interpretation emphasizes the importance of SMTZ as not only a methane sink but also an important diagenetic front for global DIC cycling. We further underscore the need to incorporate a DIC pump in methane-charged shallow marine sediments to models for coastal and geologic carbon cycling. This new understanding will… Read more »

CARBON ISOTOPE FORENSICS FOR METHANE SOURCE IDENTIFICATION.

Remediation Coffin, R., Mueller, J. Methane (CH4) in ecosystems originates from ancient petroleum formed deep within the earth and/or via microbial fermentation of organic carbon and subsequent reduction of carbon dioxide (CO2). Given the complexity of different ecosystems, origins of CH4 present can be difficult to determine. This issue was realized in a situation where an antimethanogenic in situ chemical reduction (ISCR) remedial amendment containing organic… Read more »

2023-2026 Ross Sea Antarctica

Dr. Coffin is the Principal Investigator of an National Science Foundation Sponsored Project to conduct 16 weeks at sea over two years working down in the Ross Sea off the coast of Antarctica on deep ocean warming and the volumes of methane and oil in this region. Expectations from this research include: 1) Ross Sea high resolution seismic data; 2) an expanded Antarctica coastal seismic data… Read more »

CO2 RELEASE FROM POCKMARKS ON THE CHATHAM RISE-BOUNTY TROUGH AT THE GLACIAL TERMINATION.

Paleoceanography And Paleoclimatology Stott, L., Davy, B. Shao, J. Coffin, R., Pecher, I., Neil, H., Rose, P. Seafloor pockmarks of varying size occur over an area of 50,000 km2 on the Chatham Rise, Canterbury Shelf and Inner Bounty Trough, New Zealand. The pockmarks are concentrated above the flat‐subducted Hikurangi Plateau. Echosounder data identify recurrent episodes of pockmark formation at ~100,000‐year frequency coinciding with Pleistocene glacial terminations…. Read more »
