What Dartmouth Ocean Technologies does

Dartmouth Ocean Technologies Inc. (DOT) is a privately-held Canadian manufacturer of underwater sensor and sampling technology headquartered in Dartmouth, Nova Scotia. The company designs and builds three commercial product lines: autonomous environmental DNA (eDNA) samplers (the eDNA Sampler, the NatureMetrics co-developed DOT-NM Autosampler, and the higher-volume eDNA Rapid Sampler); microfluidic Lab-on-Chip (LOC) nutrient sensors for in situ measurement of phosphate, nitrate, and total alkalinity using proprietary Inlaid Optical Cell Technology and colorimetric absorbance spectrophotometry; and the V-Wing towed underwater depressor, a portable towed body with a 5:1 lift-to-drag ratio used to carry sensor payloads without motorized propulsion. Core technology is protected by five granted US patents plus one pending application, and the underlying LOC and eDNA prototypes originated in Dr. Vincent Sieben's lab at Dalhousie University before being transferred to DOT for commercialization.

DOT sells instruments and turn-key custom platforms via a quote-based direct sales motion out of its Dartmouth headquarters, supplemented by an international sales representative network covering Spain/France, Italy, Norway/Sweden/Denmark, Korea, Scotland, Japan, England, and Australia. Revenue streams include one-time hardware sales (eDNA samplers, LOC sensors, V-Wing), consumables (reagent chemistry reloads for the LOC sensors), and project-based custom engineering for combined platform/turn-key systems. Pricing is not publicly disclosed and is negotiated per project. Customers span oil and gas (BP, TotalEnergies), offshore survey and renewables (Fugro), academic and government research (Dalhousie, University of Windsor, IOW), environmental genomics (NatureMetrics), and Canadian government/defence (Fisheries and Oceans Canada, Royal Canadian Navy, DRDC), with operational deployments ranging from the Canadian Arctic and Antarctica to the Great Lakes and UK offshore waters.

The company was founded by Arnold Furlong, a serial entrepreneur with over 40 years in the ocean-technology sector, and the leadership team includes CTO Dr. Vincent Sieben, General Manager Tom Knox, Business Development Manager Matt Dempsey, and directors covering biology, bioinformatics, business development, and innovation. Strategic channels include a flagship 2023 partnership with NatureMetrics and a 2025 integration with Fugro for offshore wind biodiversity monitoring, supported by a peer-reviewed validation library of 8+ scientific publications and OCEANS 2024 conference proceedings.

Core offering

Dartmouth Ocean Technologies Inc. (DOT) manufactures and sells underwater sensor and sampling hardware under three product lines: autonomous eDNA (environmental DNA) Samplers for biodiversity monitoring, microfluidic Lab-on-Chip nutrient sensors for in-situ measurement of phosphate, nitrate, and total alkalinity in seawater, and the V-Wing towed underwater depressor platform. The company provides individual instruments and complete turn-key integrated systems combining its sensors with towed, moored, or autonomous platforms for customers in oil & gas, offshore renewables, marine survey, academic research, and government/defence sectors worldwide.

Product overview

Dartmouth Ocean Technologies Inc. (DOT) offers a portfolio of underwater sensor and sampling technologies organized into three product lines that can be deployed together on towed or moored platforms. The eDNA product line centers on the autonomous eDNA Sampler (self-priming, self-cleaning, self-preserving), complemented by the co-developed DOT-NM Autosampler (with NatureMetrics for integrated lab analysis) and the higher-volume eDNA Rapid Sampler with nine parallel pumps. The Lab-on-Chip product line uses proprietary "Inlaid Optical Cell Technology" microfluidic sensors to deliver real-time in situ measurement of Phosphate, Nitrate, and Total Alkalinity in seawater — including a single-instrument Dual Chemistry Nitrate Phosphate Sensor — with built-in data logging, Ethernet, and serial streaming for deployment on buoys, ROVs, gliders, and profiling floats. The V-Wing towed underwater depressor provides the platform to carry these and other sensors during underwater mapping, research, inspection, and reconnaissance missions, completing DOT's end-to-end measurement solutions for oceans, lakes, and waterways.
