This post is about the new paper, which got out this week by a group of authors, including me, on databases. The title of the paper is “Palaeo sea-level and ice-sheet databases: problems, strategies and perspectives” and was published in Climate of the Past. It bases on discussions and results of a PALSEA2 meeting in 2014 in Lochinver and was compiled by many leading scientists in this field.
The fundamental question this paper addresses is how to bring the information gathered in the field are brought to those using the data for their analysis. A medium for this are databases and many scientists create their own in many different ways. But how to make them reusable by other scientists in the best possible way is a huge task. As such this paper shows some general guidelines for the workflow of database creation and which steps should be taken in the future. It focusses therein on palaeo sea-level and ice-sheet data as they are used to investigate the development of the sea-level in the past thousands and millions of years.
This post should be an introduction to some other background posts, which I intend to write in the next weeks on further details of the paper. The topics I intend to write about are
- What makes palaeo sea-level and ice-sheet data so special?
- What does ATTAC^3 mean for scientific data handling?
- Data publishing? Isn’t that a solved issue?
- Data citation and the problem with the H-index
- What can the future bring?
With these topics I hope to enlight some more details of this topic from my personal view.
The end of the year has arrived and the last conference in it will be for me the AGU 2014 in San Francisco. My contributions are fucussed on one presentation on Wednesday morning at the Session “PP31F – Sea Level, Ice Sheets, and High-Latitude Climates during Previous Warm Periods I”. My talk will give some insight on the problematics around the determination of sea-level variability during the Last Interglacial.
Observations are generally a tricky thing. Not only are they a special kind of model, which tries to cover a sometimes very complicate laboratory experiment. Additionally they are also representing the truth, as far as we are able to measure it. As a consequence they play a really important part in science, but are in some fields hard to generate.
During the PALSEA2 meeting a question has come up in the context of the generation of paleo-climatic sea-level observations.
Assumed your ressources allow only two measurements, is it better when they be near towards each other or should they be far away.
In the heat of the discussion both sides were taken, but in the end the conclusion was the typical answer for such kind of questions: “it depends on what you want to measure”. Continue reading
Last week I visited the second time a meeting of PALSEA2, this time in Lochinver, after the last one has taken place in Rome. PALSEA2 is a group of sientists, who focuses on the evaluation of paleo sea-level and causes for its change over time. Every year, a meeting takes place and brings people together to talk about this topic and how to proceed to put further constrains on future sea-level. Each meeting has a main topic and this year databases for sea-level indicators was at the top of the lists to discuss. Many interesting conversations filled the days and lead to many insights into this diverse research field.
