SMHI Oceanography, Information and Data

Oceanographic Data Center for BALTEX

We intend to develop the data centre so that registered users can select data directly from the database themselves, and have it emailed to them. While this system is under development, the current data holdings are listed on this page. At present, the available data consists of CTD profiles and transects, and sea level data.

CTD data

CTD data have been contributed to the data centre by Andreas Lehmann, of IfM-Kiel, Jan Piechura, from IO PAS, Sopot, and by SMHI, Göteborg. By clicking on the links below, you can see maps of the sampling locations, and also read a short description of the data set.

• Lehmann (Kiel) dataset
• Piechura (Sopot) dataset
• SMHI (Göteborg) dataset

IfM-Kiel CTD data

These data were collected by CTD cast, and contain pressure (dbar), temperature (°C) and conductivity (mS/cm) data. Data have been processed into 1 dbar intervals. Cruises took place at the following times:

1999 April May June July August 2000 April May July August

2001 April May July August 2002 January April May

IOPAS towed CTD data

These data were collected by IOPAS' towed CTD systems, during the BALTEX coordinated enhanced observing periods. They used either the Idronaut 316 or Seabird SBE 49 CTD (the actual instrument is indicated in the file header). Records were de-spiked and binned to 0.5 dbar levels. Data were collected during periods listed below, and an example of the data availability is presented as a cruise track, and also as an analysed transect. These figures were provided by IOPAS.

SMHI CTD data

Data were collected using SMHI's General Oceanics CTD from the R/V Argos, and contain pressure (dbar), temperature (°C), conductivity and fluorimeter data. In addition, derived parameters such as density (σ _θ) and salinity are also included. Data have been averaged into 0.5 dbar bins. The monthly distribution of CTD casts is shown in the table below. In addition to CTD profile data, SMHI has also supplied water bottle data (including nutrients) taken during the same cruises.
