Submarine Scientific LLC

Submarine Scientific LLC is an ocean science and modeling company based in San Francisco, California, in the United States. According to its official website, the company provides technical and scientific consulting intended to support the marine carbon dioxide removal (mCDR) industry as well as other ocean industries. Its work sits at the intersection of oceanography, climate technology, and data infrastructure, and it positions itself as a specialist advisory partner for marine environmental projects. The company's service offering is organized around customized and budget-friendly consulting and advisory solutions. Its stated services include customized ocean modeling, site selection, MRV (monitoring, reporting, and verification) protocol development, sensor guidance, and CO2 removal quantification. These services are aimed at clients who need scientific rigor when planning, measuring, or validating ocean-based interventions and monitoring programs. Submarine Scientific lists the industries it supports as marine carbon dioxide removal (mCDR), fisheries management, aquaculture, environmental monitoring, and offshore wind energy. This range reflects a broader ocean-services strategy: the same modeling, sensing, and quantification capabilities that serve carbon removal also apply to fisheries, aquaculture operations, environmental compliance, and offshore energy development. The company's public profile highlights a small, expert team. Its website names Veronica Tamsitt, PhD, described as an expert in ocean circulation, air-sea fluxes, and the impact of physics on ocean biogeochemistry; Jacki Long, described as an expert in synthesizing satellite and marine in-situ sensor data to study biogeochemical carbon cycling; and Jonathan Kirk, described as a veteran AI founder, startup advisor, and climate tech strategist who has started eight companies. The presence of an AI and climate-tech strategist alongside ocean scientists suggests a company that combines domain science with data and software infrastructure. Submarine Scientific is active in the emerging marine carbon dioxide removal ecosystem. Its website reports that it was awarded a Frontier Innovation grant to advance ocean modeling for marine CDR, that it sits on the steering committee at Carbon to Sea's OAE (ocean alkalinity enhancement) Model Skill Assessment Workshop, that it introduced the OAE Data Commons at a Carbon to Sea convening, that it presented advances in mCDR modeling and data infrastructure at the Ocean Sciences Meeting 2026, and that it and Carbon to Sea announced a new project to develop the OAE Data Commons platform. It has also published commentary such as "The State of the mCDR Union" and presented on trust infrastructure at the California Ocean Sciences Trust Forum on abiotic mCDR. As a private company, Submarine Scientific does not appear to be publicly listed, and no parent company or owner is identified in the available evidence. Its brand identity is tied to scientific credibility, modeling capability, and data infrastructure for ocean-based climate solutions rather than to a consumer product. The company's focus on MRV protocols, sensor guidance, and quantification aligns with the measurement and verification needs that funders and regulators increasingly require from ocean carbon removal projects.

Submarine Scientific LLC is a United States company based in San Francisco, California. Public evidence about its founding is limited; Wikidata records it as a company in San Francisco, and its official website describes it as an ocean science and modeling company. The company emerged in the context of the growing marine carbon dioxide removal (mCDR) sector, a field that gained momentum in the 2020s as governments, philanthropies, and climate funders began investing in ocean-based carbon removal research and measurement. From its public materials, Submarine Scientific built its identity around scientific consulting for ocean industries. Its website states that it provides technical and scientific consulting to support the marine carbon dioxide removal industry and other ocean industries, and that its science team offers customized and budget-friendly consulting and advisory solutions for marine environmental projects across various sectors and service domains. The listed services — customized ocean modeling, site selection, MRV protocol development, sensor guidance, and CO2 removal quantification — reflect the practical needs of projects that must be planned, monitored, and verified. The company's team includes ocean scientists and a climate-tech entrepreneur. Veronica Tamsitt, PhD, is described as an expert in ocean circulation, air-sea fluxes, and the impact of physics on ocean biogeochemistry. Jacki Long is described as an expert in synthesizing satellite and marine in-situ sensor data to study biogeochemical carbon cycling. Jonathan Kirk is described as a veteran AI founder, startup advisor, and climate tech strategist who has started eight companies. This combination points to a company that pairs oceanographic domain expertise with data and software capabilities. Submarine Scientific has become visible in the mCDR ecosystem through collaborations and public engagements. Its website reports that it was awarded a Frontier Innovation grant to advance ocean modeling for marine CDR. It has participated in Carbon to Sea's OAE Model Skill Assessment Workshop as a member of the steering committee, and it introduced the OAE Data Commons at a Carbon to Sea convening. The company and Carbon to Sea announced a new project to develop the OAE Data Commons platform, an initiative aimed at shared data infrastructure for ocean alkalinity enhancement. Submarine Scientific also presented advances in mCDR modeling and data infrastructure at the Ocean Sciences Meeting 2026, published commentary titled "The State of the mCDR Union," and presented on trust infrastructure at the California Ocean Sciences Trust Forum on abiotic mCDR. These activities indicate that the company's role extends beyond one-off consulting into building shared tools and standards for the field, particularly around modeling skill assessment and data commons. The emphasis on MRV protocols, sensor guidance, and quantification aligns with the measurement, reporting, and verification requirements that funders and regulators increasingly demand for ocean carbon removal. As a private company, Submarine Scientific does not appear to be publicly listed, and no parent company or owner is identified in the available evidence. Its history is therefore best understood as that of a young, specialist ocean-science consultancy and data-infrastructure provider operating at the intersection of climate technology and marine science.
