Definition of BOTTFLAG

BOTTFLAGDefinition
0The sampling event occurred without any incident being reported to BODC.
1The filter in an in-situ sampling pump physically ruptured during sample resulting in an unquantifiable loss of sampled material.
2Analytical evidence (e.g. surface water salinity measured on a sample collected at depth) indicates that the water sample has been contaminated by water from depths other than the depths of sampling.
3The feedback indicator on the deck unit reported that the bottle closure command had failed. General Oceanics deck units used on NERC vessels in the 80s and 90s were renowned for reporting misfires when the bottle had been closed. This flag is also suitable for when a trigger command is mistakenly sent to a bottle that has previously been fired.
4During the sampling deployment the bottle was fired in an order other than incrementing rosette position. Indicative of the potential for errors in the assignment of bottle firing depth, especially with General Oceanics rosettes.
5Water was reported to be escaping from the bottle as the rosette was being recovered.
6The bottle seals were observed to be incorrectly seated and the bottle was only part full of water on recovery.
7Either the bottle was found to contain no sample on recovery or there was no bottle fitted to the rosette position fired (but SBE35 record may exist).
8There is reason to doubt the accuracy of the sampling depth associated with the sample.
9The bottle air vent had not been closed prior to deployment giving rise to a risk of sample contamination through leakage.

Definition of Rank

  • Rank 1 is a one-dimensional parameter
  • Rank 2 is a two-dimensional parameter
  • Rank 0 is a one-dimensional parameter describing the second dimension of a two-dimensional parameter (e.g. bin depths for moored ADCP data)

Narrative Documents

Niskin Bottle

The Niskin bottle is a device used by oceanographers to collect subsurface seawater samples. It is a plastic bottle with caps and rubber seals at each end and is deployed with the caps held open, allowing free-flushing of the bottle as it moves through the water column.

Standard Niskin

The standard version of the bottle includes a plastic-coated metal spring or elastic cord running through the interior of the bottle that joins the two caps, and the caps are held open against the spring by plastic lanyards. When the bottle reaches the desired depth the lanyards are released by a pressure-actuated switch, command signal or messenger weight and the caps are forced shut and sealed, trapping the seawater sample.

Lever Action Niskin

The Lever Action Niskin Bottle differs from the standard version, in that the caps are held open during deployment by externally mounted stainless steel springs rather than an internal spring or cord. Lever Action Niskins are recommended for applications where a completely clear sample chamber is critical or for use in deep cold water.

Clean Sampling

A modified version of the standard Niskin bottle has been developed for clean sampling. This is teflon-coated and uses a latex cord to close the caps rather than a metal spring. The clean version of the Levered Action Niskin bottle is also teflon-coated and uses epoxy covered springs in place of the stainless steel springs. These bottles are specifically designed to minimise metal contamination when sampling trace metals.

Deployment

Bottles may be deployed singly clamped to a wire or in groups of up to 48 on a rosette. Standard bottles have a capacity between 1.7 and 30 L, while Lever Action bottles have a capacity between 1.7 and 12 L. Reversing thermometers may be attached to a spring-loaded disk that rotates through 180° on bottle closure.

UKOA D366 dissolved methane (CH4) and nitrous oxide (N2O) concentrations from CTD bottle and bioassay samples

Originator's Protocol for Data Acquisition and Analysis

Samples were collected from 36 CTD profiles from between 1 and 10 depths for each CTD. Then 1 litre samples were equilibrated with compressed air and headspace analysis performed onboard using FID-gas chromatography and ECD-gas chromatography for CH4 and N2O respectively. Atmospheric concentrations were determined by the same methods using a pumped supply from the ships monkey island.

Additionally, methane and nitrous oxide were sampled from 5 bioassay experiments during the cruise, that were designed to evaluate the response of multiple organisms and processes to artificial carbonate system manipulation. An extra 3 nutrient addition experiments were also conducted onboard. The incubations were performed within a purpose-built experimental laboratory allowing acute temperature and light control. The temperature in the container was set to match the in situ at the time of the water collection. The light (100 µE. m-2. s-1) was provided by LED panels and remained constant through the cruise. A 14/8 h light/dark cycle was applied. Each of the 5 bioassays were run for 4 days with 2 time points: T1 (48h) and T2 (96h). In order to provide enough water to process the various analyses and to have triplicate of each measurement, 9 bottles were dedicated to each time point. A total of 72 bottles were set up for each bioassay and arranged on shelves in the container. At pre-dawn, surface water (~ 5m deep) was collected from Niskin bottles (24 X 20L) out of one single cast and immediately dispatched in transparent acid-cleaned 4L polycarbonate bottles on deck. The bottles were then wrapped individually in zip lock bags to avoid contamination pending carbonate chemistry manipulations. Bioassay samples were analysed in the same way as the CTD samples.

BODC Data Processing Procedures

Data were submitted via email in an Excel spreadsheet archived under BODC's accession number PML120178. Sample metadata (Date, Julian Day, Time, CTD cast, position, bottle number and depth) were checked against information held in the database. There were no discrepancies.

The concentration data were provided in nano-moles per litre. These units match the BODC parameter code units and a unit conversion was not applied. Where replicate measurements were provided the mean and standard deviation were calculated and loaded to the database.

The data were reformatted and loaded in BODC's samples database under Oracle Relational Database Management System. Data were marked up with BODC parameter codes and loaded into the database.

A parameter mapping table is provided below;

Project Information

UKOARP Theme B: Ocean acidification impacts on sea surface biology, biogeochemistry and climate

The overall aim of this theme is to obtain a quantitative understanding of the impact of ocean acidification (OA) on the surface ocean biology and ecosystem and on the role of the surface ocean within the overall Earth System.

The aims of the theme are:

  • To ascertain the impact of OA on planktonic organisms (in terms of physiological impacts, morphology, population abundances and community composition).
  • To quantify the impacts of OA on biogeochemical processes affecting the ocean carbon cycle (both directly and indirectly, such as via availability of bio-limiting nutrients).
  • To quantify the impacts of OA on the air-sea flux of climate active gases (DMS and N2O in particular).

The main consortium activities will consist of in-situ measurements on three dedicated cruises, as well as on-deck bioassay experiments probing the response of the in-situ community to elevated CO2. Most of the planned work will be carried out on the three cruises to locations with strong gradients in seawater carbon chemistry and pH; the Arctic Ocean, around the British Isles and the Southern Ocean.
