Ocean phytoplankton productivity from 1970 to 1994
- Abstract
-
This dataset integrates data on phytoplankton chlorophyll and primary production estimeted by using the C-14 methods, collected during several research cruise between 1970 and 1994. The reported data were collected during the tropical ocean cruise and the Atlantic Ocean cruise along the North American coast. The dataset has been created using online data available from Ocean Productivity website.
- purpose
-
This dataset has been used as a case study within the Biomass Virtual Research Environment, in particular in workflow 1 and workflow 4.

- Abstract
-
Most critical issues currently faced by our society involve key environmental challenges. Pollution, land use and climate change, and their impacts on biodiversity and ecosystem integrity need to be urgently addressed, providing quantitative knowledge to be transformed into actionable strategies. Given the complexity of such challenges, a multi-disciplinary approach to the Earth System is deemed crucial. This approach involves combining field and laboratory measurements, analyses, experiments, data analysis, and modeling tools across the various interlinked environmental domains. Italy is actively involved in all major pan-European Environmental Research Infrastructures (RIs) and also hosts other nationally relevant RIs, all essential for providing the systematic and coherent information needed for high-level research. Given the large number and heterogeneity of these infrastructures, coordinated actions are essential to integrate and interlink them, as well as to harmonize their activities. To achieve an integrated approach to the Earth system and its changes, the 22 participating RIs agreed to jointly prepare and build the thematic network called ITINERIS. The primary objective of ITINERIS is to establish the italian integrated system of the Research Infrastructures in the environmental scientific domain, facilitating observation and study of processes in the atmosphere, marine domain, terrestrial biosphere, and geosphere. Such a broad-scale and long-term vision of environmental research, sustained by the main Italian scientists currently involved in European RIs, is truly innovative and it will support Italy in taking a leading role in European environmental research activities, designing the framework for the next decades.

- Description
-
The dataset is a subset of data from the Ocean Productivity website https://orca.science.oregonstate.edu/index.php. The data were selected searching for specific variables and only data were the variables of interests were present (e.g. temperature, irradiance, day light and depth) were selected. Water samples have been collected during different research cruise for estimating phytoplankton physiology and photosynthesis, by measuring daily carbon fixation rates and chlorophyll a content. The "Distance from coast" was estimated using the geographic coordinates of the sampling point in relation to the coastline.

Workflow
- Definition
-
The process that is used to produce a specific research result in a concrete domain. A workflow comprises a series of components that are arranged in a directed graph to set the order of execution of such components. Therefore, a workflow is usually a complex process and may involve both automatic and manual procedures for dealing with research objects and documenting them. Workflows may need instantiation in terms of input data and process parameters.
