TC23031 Survey Water Sample Analysis

Project Aims

JNCC wishes to commission a contract to undertake the analysis of water samples to be collected on the TC23031 offshore survey. There are up to 50 water sampling locations to be sampled on this survey, each consisting of suit of samples acquired at up to three depths, totalling a maximum of 150 sampling events.

Option 1

Please provide quote for complete analysis of up to 150 nutrient samples and 150 THC samples and draft deliverables by March 8th 2024, any remedial action to be completed by 22nd March 2024.

Option 2

Please provide a quote for the cost and breakdown of the number of samples that can be completed by March 8th, 2024, with expectation of completing remaining samples in following financial year by end of Q1 of financial year 24/25 (remedial action complete by 30th June 2024). In your quote, please detail the cost per sample completed in financial year 23/24 and the cost per sample completed in financial year 24/25 including an estimate of the completion timeframe.

Option 3

Please provide a quote for the cost and breakdown of timings for completion of up to 150 nutrient samples and 150 THC samples by end of financial year 2024/2025.

Project Background

JNCC will be undertaking an offshore seabed survey to the Dolphin Head (DH hereafter) and North East of Farnes Deep (NEFD hereafter) HPMA's onboard the Marine Research Vessel (MRV) Tom Crean (survey code TC23031).

The TC23031 survey will depart from Portland on 13th September 2023 and return to Aberdeen on approx. 10th October 2023.

JNCC wishes to commission a contract to undertake nutrient and total hydrocarbon content (THC) analysis of 150 water samples collected on this survey.

NEFD and DH lie in offshore waters to the east of Northumberland and south of Sussex respectively. For more information regarding NEFD and DH please see https://jncc.gov.uk/our-work/north-east-of-farnes-deep-mpa-and-hpma/ and https://jncc.gov.uk/our-work/dolphin-head-hpma/.

Sampling will be conducted using a Niskin bottle rosette sampler onboard the R/V Tom Crean.

Seawater will be collected from each depth/station and frozen in a 1L plastic bottle with approximately 5cm of headspace air for analysis of; ammonia, nitrate, nitrite, and phosphate. An additional 1L glass bottle of water will be collected and frozen for analysis of total hydrocarbon content (THC).This will result in final sample numbers of up to 150 samples stored in plastic bottles for nutrient analysis, and 150 samples stored in glass bottles for THC
