Описание (английский):

Provides guidance on the principles to be applied to the design of sampling programmes, sampling techniques and the handling and preservation of samples of sea water from tidal waters. Does not apply to the collection of samples for microbiological or biological examination. The main objectives are quality characterization measurement, quality control measurement, measurements for specific reasons, and examination of the effects of man-made structures.

Overview

ISO 5667-9:1992 - Water quality - Sampling - Part 9: Guidance on sampling from marine waters provides practical guidance for designing sampling programmes, choosing sampling techniques, and handling and preserving sea water samples from tidal waters (estuaries, tidal inlets, coastal zones and the open sea). It focuses on chemical and physical determinands and explicitly excludes collection methods for microbiological or biological examinations (see ISO 8199 for microbiology). Main objectives include quality characterization, long‑term quality control, investigations for specific causes, and assessing effects of man‑made structures.

Key topics and technical requirements

Scope & objectives: Guidance for tidal and marine waters including spatial/temporal characterisation, trend monitoring and impact assessment of structures (ports, jetties, barrages).

Sampling programme design: Emphasis on preliminary surveys and statistical planning to locate representative sampling points (depth profiles, area profiles, spot and composite samples).

Sample types: Definitions and use of spot samples, depth profile samples, area profile samples, and composite samples (time/flow‑weighted).

Containers & contamination control: Prefer glass or inert materials; avoid fragile containers at sea. Minimise absorption and contamination (use gloves, wash bottles before collection).

Sampling equipment:

Open samplers for surface or near‑surface collection (avoid for subsurface due to microlayer contamination).
Closed‑pipe samplers (tube samplers with valves/stoppers) for defined depths and depth‑integrated composites - internal PTFE coatings and PTFE/silicone seals recommended where contamination risk exists.
Pumping devices (peristaltic/centrifugal) for dissolved and particulate chemical determinands; not ideal for volatile/gaseous compounds.
Automatic samplers and integrated monitoring stations for timed discrete sampling, often combined with data loggers and telemetry.

Operational guidance: Use non‑metallic hydrographic cables for trace metal/hydrocarbon work; allow samplers to “acclimatize” (approx. 5 minutes) before taking samples; avoid rubber internal springs, and use plastic‑coated messenger weights where needed.

Special considerations: Surface microlayer sampling is difficult to make representative; seabed samples require purpose‑designed devices; tidal excursion and currents must be considered to avoid duplicate sampling of the same water.

Applications

Coastal and estuarine monitoring and compliance

Long‑term trend and baseline studies (water quality characterization)

Effluent/contaminant plume tracing and incident response

Environmental impact assessments for marine infrastructure

Design of sampling protocols for research cruises and monitoring stations
