The Arctic data represents one of the longest planktonic time series data sets available and as such is invaluable in our GreenSeas research. The earliest zooplankton are from 1913 and phytoplankton from 1921. In addition to this there are a sparse range of environmental & physical measures, including sea-ice extent. There is also included a high frequency, hourly (for 12 days), chlorophyll, temperature & salinity surface (5m) flow transect that covers a 5 x 7 degree spatial area.
Sample depths = 0 to 380m.
Data collection commentary: during M1-18 the MMBI team lost a key data programmer, so processing of post 1999 plankton data and inclusion of all environmental & physical variables was held up. We now have the post 1999 temperature & salinity measures. The staffing issue is being resolved (Q3/Q4 2012) through employing a local GIS specialist to process their access and excel based data.


These are two point source time series marine stations that provide a regular set of time series with many months repeated for the one near Iceland (1991 – 2006) and a high weekly coverage resolution for station Mike (latitude : 66, longitude: 2). The data includes physical, nutrients, some chlorophyll, alkalinity, oxygen & dissolved in-organic carbon.
Depths= 0 to 2000m.
Data collection commentary: the Nordic points are extra data added into the consortium and have an excellent detail resolution: both the provision of details, time sampling, Meta data and conversion factors. This latter knowledge has been useful for the merging of information in the other regions in the analytical database.


The Atlantic Meridional Transect (AMT) data represents the majority of the latitudinal gradient across the Atlantic and present a substantial longer term dataset. This AMT observatory data ranges from +50 deg N to -51 deg N and this time series runs from 1995 to 2010+. The results from this observatory benefit this work by repeated sampling along the same longitudinal and latitudinal transect. The spatio-temporal time series has daily measures from months typically in April / May and Sept/ Oct / Nov. Depths= 0 to 500m typically (and very occasionally to 5000m).
Summaries of the raw data are looked after by the BODC, UK and we have with their assistance, and according to their/our data sharing policy extracted data from AMT 1 – 16 (1995 to 2005). In addition to this, from collaborative work with other scientists at PML, we have also included processed depth profile data where chlorophyll, temperature, dissolved oxygen, nutrient and mixed layer depth knowledge from 1995 – 2010+ are included into the database. This processed data (n=1187) represents a significant amount of work that has included ‘data cleaning' raw depth profile data so that properties of plankton can be examined at the surface, deep chlorophyll max depth, nutricline and mixed layer depths.
Data collection commentary: The full BODC database has detailed Meta data, which explains the fields, measures and the originators / PI. The originator / PI's latter in some cases vary over the years so please refer to the attached bottle measures files for AMT1-11 and AMT12-16 should you require more details for specific measures. These BODC variable codes are also listed in the GreenSeas WP2 & 4 work directory.
PML and NERC in the UK represent a cross-disciplinary marine research hub, and this project builds on this knowledge through looking at the strategic longer term climate impacts of information collected over many years. Due to this, and to disseminate foreground generated by the project, we have established a seasonal Atlantic Observatory Discussion Forum as GreenSeas initiative at PML/NERC. So far we have had contributed talks / discussion from 15 researchers during Q1-Q3 2012 in this ‘Atlantic Forum' with audiences of 20-30 scientists regularly contributing.
The MB95-01 cruise is downloaded from, and a subset of paramters: salinity and temperature is used in this database.

Southern Ocean

The Southern Ocean was identified in our scientific question and theme sessions (Section 2) as one of the locations where our expectation of accurate numerical model performance is low, simply because research transects in the Southern Ocean are exceptionally challenging and so historical data is sparse. Together with the three Southern Ocean data collection partners: University of Cape Town (UCT) , UNI Research (Uni-Res, Norway) and the Council for Scientific and Industrial Research (CSIR) we have combined these data outputs into the analytical database. In summary this combined SO data has:
UCT Depths = 0 to 500m, and years 1985 to 2008 including 7 sampling transects.
Uni-Res Depths = 0 to 5000m, and years 92 and 98.
CSIR Depths = 0 to 500m, with the SANAE research programme 2008 to 2011+.
Data collection commentary: In the Southern Ocean data team, there was an initial concern about data overlaps. The combined data provides a good range of time, depth and measures and so the combination coverage is complementary. The early UCT data required some intensive data archaeology and benefitted from a visit of PhD student to PML (both processing experimental samples and completing the re-digitisation and combination the early data for this task). Recent SANAE depth profile data is sampled at such a high frequency the raw data files required Matlab pre-processing to extract relevant detail. The Uni-Res information provides some deep samples and plankton taxonomy not available in the other early UCT data.
