OSMOSIS Cruise D381A moored Star-Oddi Thermistors: Quality Report

Data quality issues were observed by the originator, which have been outlined below for future user awareness.

The temperature data collected here are much poorer than those from the MicroCATs.

The following sensors were judged to have poor data and recorded as such in the JC090 log:

s/n 4186 - lost
s/n 4263 - flooded
s/n 4236 - unable to connect
s/n 3114 - unable to connect
s/n 4204 - very short data record

The originator has placed thermistor T4218 within the NW-Inner mooring but was unable to cross-reference its location using either the deployment or recovery cruise reports. It should be noted that the temperature appears to be affected significantly by surface warming (very warm in September 2012 and September 2013) so it is likely near the top. The originator has placed suspect quality flags on the pressure channel for this reason which are flagged 'L' in the file.

The originator has applied poor quality flags to the pressure channel on the South West mooring on the following serial numbers due to pressure data from the nearest MicroCAT being poor and so replaced with that from the neighboring Nortek Aquadopp (SW Inner, 8080):
s/n 4199
s/n 4200
s/n 4201
s/n 4202
s/n 4203
s/n 4205
s/n 4206

During BODC quality control procedures, BODC have applied additional 'M' flags where the data values for temperature were significantly noisy at the beginning and end of the data collection period.

It should be noted that BODC has taken a high level approach and therefore further quality control has been left to the discretion of the end user.

Narrative Documents

Sea-Bird SBE 37-SM MicroCAT

The SBE 37-SM MicroCAT is a high accuracy conductivity and temperature recorder (pressure optional). Designed for moorings and other long-duration, fixed-site deployments, MicroCATs have non-corroding titanium housings rated for operation to 7000 metres or pressure sensor full scale-range. Communication with the MicroCAT is over an internal, 3-wire, RS-232C link. The MicroCAT's aged and pressure-protected thermistor has a long history of exceptional accuracy and stability (typical drift is less than 0.002° per year). Electrical isolation of the conductivity electronics eliminates any possibility of ground-loop noise.

OSMOSIS Cruise D381A moored Star-Oddi Thermistors: Originator's Data Processing

The originator has supplied Star-Oddi temperature logger data from inner mooring sites (NW, NE, SW, SE) and a central mooring site as part of the Ocean Surface Mixing, Ocean Sub mesoscale Interaction Study (OSMOSIS) consortium project.

The moorings were deployed on the RRS Discovery Cruise D381A in 2012 and were recovered a year later on the RRS James Cook Cruise JC090.

Originator's Data Processing

Temperature measurements were collected as part of the OSMOSIS experiment in the eastern North Atlantic. These data were obtained on a suite of five (5) moorings during September 2012-September 2013 and, therefore, contain mooring motion. They have been modified from their original measurements in order to correct for temperature biases. Wild-point editing were also applied to the noisy data. The originator has noted that pressure was not recorded on these data but was inferred from "known" positions on the mooring with respect to CTD locations (see Allen et al. 2013 D381 cruise report). Thus, these depths may be incorrect. Also, that for an unknown reasons, there does not seem to be a CTD cast coincident with MicroCAT measurements during the recovery period. Thus, no calibration curve exists. The original data can be obtained upon request.

Data have been cropped to the times during which the moorings were placed in the water (September 2012) and recovered (September 2013). This was ascertained from the pressure sensor on each instrument.

The originator has applied the following processing steps to each Star-Oddi Starmon file.

Read from .DAT file
Read into matlab and placed into large structure
Sorted depths
Looped over plots to assess data quality; made notes as appropriate (described below)

The originator took the additional following steps due to noise within these data to ensure data were of fair quality:

1. Determine the "quality" of each sensor's data (quality_check1.m)
* loop over each thermistor record and plot each data record visually
* manually assign a quality flag to the data (1 good, 2 potentially bad or 3 bad)
* in this pass, a quality flag (i.e., quality_flag) of 3 was given to data having spikes (or wild points)

2. Eliminate spikes or wild points within those records whose quality_flag = 3 (wild_point_editor.m)
* wild points are defined as those data points whose value exceeds a difference from the local mean of 7.1 times the local standard deviation.
* the kernel used to define the local mean and local standard dev is a 1-day (721-pixel) window centred on each data point
* wild points are replaced with the median value of data within the same window
* we retain the original data in the field "temperature"
* the (filtered) record is placed within a variable called "temperature_modified";
* the quality_flag is set to 2

Some records which pass this automated step are of poor quality. This is because the local standard deviation is large due to the outliers themselves. A subsequent step ensures data within the "temperature_modified" field is of superb quality.

3. Determine the "quality" of each sensor's data (quality_check2.m)
In this step, we correct those records which were not corrected in the preceding step.
* loop over each thermistor record and plot data visually
* we examine the "temperature_modified" field rather than the "temperature" field
* we correct those records whose quality_flag = 2 in the following manner:

a) if quality_flag = 2, we look at the time-series plot
(i) if it looks ok, we do not do anything but set the quality_flag = 1
(ii) if it does not look ok (for example, due to spikes), we run a subroutine called "use_with_quality_check2.m" and graphically define the data of interest using a plot of the mean temperature record vs the observed temperature record. The objective in this "expert-based" classifier algorithm is to separate the dense "cloud" of data points from the outliers. As this is a subjective process, the user of data within the "temperature_modified" variable should use caution. We made the following decision with regard to the "quality_flag" when processing the data in this manner:
* if the edges/borders of the dense cloud of data are clearly defined, we modify the "temperature_modified" time series and set quality_flag = 1.
* if the edges/borders of the dense cloud of data are not clearly defined, we modify the "temperature_modified" time series and set quality_flag = 2.

In this manner, the value of "quality_flag" represents the quality of the "temperature_modified" field rather than the "temperature" field. The user can distinguish between good original data and good modified data by noting that good original data does not have an associated "temperature_modified" record (i.e., it is an empty vector).

b) if quality_flag = 1 or quality_flag = 3, we do not modify the data

BODC image

Figure 1. Annual average of thermistor temperatures (red, triangle) and microCAT CTD temperatures (blue, circles) and salinity (red, circles); depths correspond to the annual mean depths of each sensor over the year.

While temperature shows a very nice (canonical) shape with depth, salinity shows some scatter relative to a fifth-order polynomial fit. Thermistor temperature is slightly colder than CTD temperatures for the same depth. This suggests incorrect but consistent spacing between thermistors and MicroCAT CTDs.

OSMOSIS Cruise D381A moored Star-Oddi Thermistors: Processing by BODC

Data from 243 Star-Oddi thermistors were submitted to BODC as Matlab files, one file for each sensor. The table below describes the originators variables and how they were mapped to appropriate BODC parameter codes for standardisation purposes.

Originator's variables Originator's units Description BODC code BODC units Comments
Temperature °C Temperature of the water body TEMPPR01 °C  
Temperature_modified °C Temperature of the water body TEMPPR01 °C Present in some files that required extra quality control steps.
Pressure db Pressure (measured variable) exerted by the water body by semi-fixed moored SBE MicroCAT and interpolation between instruments with pressure sensors PREXSINT db Pressure was not recorded on these data but was inferred from "known" positions on the mooring with respect to MicroCAT locations

Please note if only the temperature variable was populated in the file this was taken through, but if both temperature and temperature_modified variables were populated only the quality controlled temperature_modified variable was taken through. The basis of how this was determined is described in the originator's processing notes. The original files are available on request.

The data were visualised in internal built software EDSERPLO. Suspect data were flagged according. Missing data values were set to appropriate values and flagged. All data files were modified by the originator, to remove data points collected during the deployment and recovery of instrumentation.


Project Information

Ocean Surface Mixing, Ocean Sub-mesoscale Interaction Study (OSMOSIS)

Background

The Ocean Surface Mixing, Ocean Sub-mesoscale Interaction Study (OSMOSIS) consortium was funded to deliver NERC's Ocean Surface Boundary Layer (OSBL) programme. Commencing in 2011, this multiple year study will combine traditional observational techniques, such as moorings and CTDs, with the latest autonomous sampling technologies (including ocean gliders), capable of delivering near real-time scientific measurements through the water column.

The OSMOSIS consortium aims to improve understanding of the OSBL, the interface between the atmosphere and the deeper ocean. This layer of the water column is thought to play a pivotal role in global climate and the productivity of our oceans.

OSMOSIS involves collaborations between scientists at various universities (Reading, Oxford, Bangor, Southampton and East Anglia) together with researchers at the National Oceanography Centre (NOC), Scottish Association for Marine Science (SAMS) and Plymouth Marine Laboratory (PML). In addition, there are a number of project partners linked to the consortium.

Scientific Objectives

  • The primary goal of the fieldwork component of OSMOSIS is to obtain a year-long time series of the properties of the OSBL and its controlling 3D physical processes. This is achieved with an array of moorings (two nested clusters of 4 moorings, each centred around a central mooring) and gliders deployed near the Porcupine Abyssal Plain (PAP) observatory. Data obtained from this campaign will help with the understanding of these processes and subsequent development of associated parameterisations.
  • OSMOSIS will attempt to create parameterisations for the processes which determine the evolving stratification and potential vorticity budgets of the OSBL.
  • The overall legacy of OSMOSIS will be to develop new (physically based and observationally supported) parameterisations of processes that deepen and shoal the OSBL, and to implement and evaluate these parameterisations in a state-of-the-art global coupled climate model, facilitating improved weather and climate predictions.

Fieldwork

Three cruises are directly associated with the OSMOSIS consortium. Preliminary exploratory work in the Clyde Sea (September 2011) to hone techniques and strategies, followed by a mooring deployment and recovery cruise in the vicinity of the Porcupine Abyssal Plain (PAP) observatory (in late Summer 2012 and 2013 respectively). Additional opportunist ship time being factored in to support the ambitious glider operations associated with OSMOSIS.

Instrumentation

Types of instrumentation and measurements associated with the OSMOSIS observational campaign:

  • Ocean gliders
  • Wave rider buoys
  • Towed SeaSoar surveys
  • Microshear measurements
  • Moored current meters, conductivity-temperature sensors and ADCPs
  • Traditional shipboard measurements (including CTD, underway, discrete nutrients, LADCP, ADCP).

OSMOSIS centre mooring

The short term moorings were deployed and recovered during cruise RRS Discovery D381A as part of the Ocean Surface Mixing, Ocean Submesoscale Interaction Study (OSMOSIS) project.

The target for the centre mooring was 48° 41.340' N, 16° 11.400' W in approximately 4,830 m of water. The mooring consisted of 48 Star-Oddi thermistors, one upward pointing 75 kHz ADCP, four 600 kHz ADCPs, thirteen Nortek single-point current meters and thirteen SBE 37 MicroCAT sensors. In addition, a light and Argo tag were fixed at the top of the mooring.
