CTD measurements
Conductivity, temperature, and pressure-derived depth in one compact autonomous field unit.
Deepod is a compact autonomous CTD and data logger for scientific field campaigns, environmental baseline work, and distributed water monitoring. It measures conductivity, temperature, and depth while keeping deployment, calibration, and data access simple.
Deepod separates the reusable electronics body from the calibrated wet-end plug. This keeps the main instrument in service while allowing the measurement-critical wet end to be exchanged, refurbished, or recalibrated between deployment cycles.
Conductivity, temperature, and pressure-derived depth in one compact autonomous field unit.
Each calibrated plug carries its own identity and calibration record, supporting replacement, refurbishment, and lifecycle tracking.
Battery operation, local storage, optional GPS, Wi-Fi offload, and browser-based configuration without phone-app dependence.
Deepod is designed for practical mounting on field frames, buoys, moorings, lines, weights, vehicles, or existing research infrastructure.
Deepod is not intended to replace accredited reference instruments. It complements them by making broader baseline coverage practical and by adding deployment context, calibration traceability, and campaign-based data access.
Deepod is intended to complement larger and more expensive reference systems by making additional deployment points practical.
The small form factor allows the unit to be attached directly to existing research infrastructure, moorings, deployment frames, diver equipment, or larger CTD systems without significantly increasing handling burden.
Deepod links each measurement to wet-end identity, factory calibration records, user one-point calibration history, deployment metadata, timestamps, and optional position data.
Sensor plugs are factory characterized using controlled multi-point calibration workflows before delivery.
User one-point calibrations are stored as part of the plug history, allowing drift and correction trends to be reviewed over time.
Exported datasets can include measurements, calibration state, timestamps, position, deployment metadata, and wet-end history.
Deepod plugs are calibrated in a controlled multi-point workflow using automated handling and reference liquids. The process is designed around repeatability, plug traceability, and practical long-term service handling.
Quick pre- and post-deployment checks help confirm expected sensor behavior before field use and after recovery.
Deepod links measurements, wet-end identity, calibration history, timestamps, deployment metadata, and optional positioning into one deployment record rather than treating measurements as isolated files.
Each calibrated plug carries its own serial identity and calibration history, allowing measurements to remain linked to the exact sensing interface used during deployment.
Factory characterization, user one-point adjustments, and calibration-related changes remain associated with the plug over time.
Exported datasets can include calibration state, deployment metadata, timestamps, positioning, and wet-end history together with the recorded measurements.
Deepod is organized around deployments and campaigns rather than isolated instruments. Multiple devices can be grouped under one shared project workflow with lightweight access and export handling.
Project leads configure deployment profiles, sampling behavior, calibration checks, and campaign handling through the built-in web interface.
Field users power on the unit and deploy it. LED feedback provides basic operational status without requiring technical interaction.
Measurements are stored locally first and transferred by Wi-Fi when available for review, campaign access, and export-oriented workflows.
Typical values depend on configuration and plug type. Final project suitability should be confirmed before deployment.
| Measurements | Conductivity, temperature, and pressure-derived depth. Optional optical and positioning features depending on configuration. |
|---|---|
| Depth rating | Short-term use up to 100 m. Long-term deployment up to 30 m. |

| Sampling | Configurable from 1 Hz to long-interval RTC operation, including hourly, daily, or weekly scheduled measurements. |
| Communication | Wi-Fi cloud offload via MQTT. Optional RS485 / Modbus variant for integration use cases. |
| Power | Rechargeable internal Li-ion battery. Charging through external stainless charging pins and 5 V charging stand. |
Current users can access deployment status, campaign summaries, device data, plug history, and export-oriented workflows through the Deepod web portal.
The portal provides lightweight access for project leads and field users without requiring a dedicated phone app or account-based workflow.
Open Deepod data portalDeepod is currently available by direct contact for research groups, monitoring projects, and selected professional users. Production capacity is intentionally limited while the platform, calibration workflow, and service loop are scaled.
