WP3. Contamination


Wp3 contamination1

WP3. Contamination

  • MSFD descriptor 8: contaminants

  • Parameters of interest

    • Identification of longest time series

      • PCB and heavy metal data in sediment and biota: 1971

    • Identification of parameters and metadata that has to be recovered

  • iota

  • S

Issue & aim

Kick-off 4DEMON , RBINS, 13 March 2014

WP3. Contamination

Inventarisation of methodology

Meeting CODA 03 Februari 2014

- Data originator heavy metals biota/sediment

  • Presence of historical samples

  • Method reconstruction

WP3. Contamination

Kick-off 4DEMON , RBINS, 13 March 2014


Wp3 contamination10

WP3. Contamination

  • Issues & approach

    • Retrieving missing metadata

    • Error estimation on historical data

      • Assess quality of data (intercalibration test & excercises, QUASH reports, …)

    • Normalization of historical data

    • Spatial and temporal calibration + data bining

Quality Control & Intercalibration

Kick-off 4DEMON , RBINS, 13 March 2014


Wp3 contamination11

WP3. Contamination

  • Issues & approach biota

  • Select the organisms to focus on

  • Identify sampling location

  • Identifymethodandmethod changes

  • Issues & approach sediment

  • Identify method and method changes

  • Normalization

    • Search for methodology of co-factors (including pretreatment)

    • Additional sampling

    • Test suitability of normalizers

  • Spatial clustering (changed position of stations)

Quality Control & Intercalibration

Kick-off 4DEMON , RBINS, 13 March 2014


Wp3 contamination12

WP3. Contamination

Project Sea

metals, pesticides, PCBs, granulometry, organic matter, loss on ignition

To check at originators laboratory

Availability vs needs: sediment

Kick-off 4DEMON , RBINS, 13 March 2014


Wp3 contamination13

WP3. Contamination

Quality Control & Intercalibration: normalization

Kick-off 4DEMON , RBINS, 13 March 2014


Wp3 contamination14

WP3. Contamination

  • Quality/methodology of potential cofactors

Quality Control & Intercalibration: normalization

TOC at W01, W02, W03 since ‘90

TOC at W01, W02, W03 since ‘71

Kick-off 4DEMON , RBINS, 13 March 2014


Wp3 contamination15

WP3. Contamination

  • Quality/methodology of potential cofactors

  • To compare analyses on different fractions

  • Recalculated to 37 µm

Quality Control & Intercalibration: normalization

Kick-off 4DEMON , RBINS, 13 March 2014


Wp3 contamination16

WP3. Contamination

  • Continue inventory and data collection

    • Contact data originators for additional data and metadata to be recovered – june 2014

      • Search for methodology of co-factors for sediment (including pretreatment)

  • Identify priority data to digitize and integrate – july 2014

    • Digitization and integration june 2014 -

  • Normalization sediment

    • Additional sampling: program to be defined before Belgica coordination meeting 2015 – september 2014
