Study Summary
Concise project description, objectives, sponsor or funder, and expected deliverables; includes start and end dates.
A complete Research Sonde Study standardizes procedures, reduces measurement error, and documents responsibilities and data handling rules, which supports reproducible results and regulatory or funder audits.
The Research Sonde Study is completed by project teams and approved by institutional authorities prior to field deployment.
Different organizations require different signatories; the three profiles below represent the most common participants.
The principal investigator signs to attest that the protocol reflects the study design, that required approvals (IRB, IACUC, or permitting) are obtained, and that data will be managed according to the stated retention and access rules.
An institutional official or lab director signs to confirm organizational approval for deployment, liability coverage, safety checks, and that training and oversight are in place for field personnel.
Concise project description, objectives, sponsor or funder, and expected deliverables; includes start and end dates.
Make, model, serial numbers, calibration dates, and spare-parts list for every sonde and accessory used in the study.
Locations (GPS), sampling frequency, depth/time parameters, and chain-of-custody procedures for physical samples.
Format, metadata standards, storage location, access controls, retention period, and disposition plan for raw and processed data.
Required permits, environmental checks, emergency contacts, PPE requirements, and insurance or liability disclaimers.
Designated signers, signature blocks, approval dates, and references to attached institutional authorizations or IRB letters.
| Field | Configuration |
|---|---|
| Signing Order | Sequential or parallel based on institutional policy |
| Authentication | Email link; add SMS code or KBA for higher assurance |
| Attachments | Allow required permit PDFs and calibration certificates |
| Retention | Enable export to institutional archive and set retention policy |
Choose a platform that supports secure PDF, audit trails, and integrations with storage or project systems.
Date work may begin after all approvals and signatures are complete
Institutional review or permits often require 4–8 weeks depending on complexity
Calibrate sondes within 30 days prior to deployment where protocol requires it
Report or archive raw data within project-defined window, typically 30–90 days
Retention periods begin on the Effective Date or on data creation
Prepare the study protocol and equipment lists before review.
Secure safety and institutional approvals, confirm insurance and permits.
Deploy sondes per the sampling plan, recording chain-of-custody.
Validate data, submit to repository, and apply retention policy.
Optica standardized field forms and reduced signer confusion by using a single template with embedded fields
A small operator digitized permission and equipment checklists to accelerate approvals
