Privacy Police

Dear visitors to the Internet portal of Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI).
To ensure that you feel secure when visiting our website, we would like to inform you below about how we handle your data. We neither publish your data nor pass it on to third parties without your consent. Below we explain what types of data we collect when you visit our web pages and precisely how it is used:

General information

Extent of data processing

We only process personal data collected from our users insofar as this is necessary for the provision of a functional web presence and our content and services. As a rule, personal data provided by our users is only processed with their consent. One exception is where statutory regulations permit the processing of data.

Legal basis for data processing

Art. 6 (1)(a) of the EU General Data Protection Regulation (GDPR) serves as the legal basis whenever we obtain the consent of the person concerned (“data subject”) for the processing of their personal data.

Art. 6 (1)(b) of the EU General Data Protection Regulation (GDPR) serves as the legal basis for the processing of personal data which is necessary for performing a contract to which the data subject is a party. The same applies to processing that is required for carrying out pre-contractual measures.

Art. 6 (1)(f) of the EU General Data Protection Regulation (GDPR) serves as the legal basis when processing is necessary to safeguard a legitimate interest of AWI or a third party, and provided this legitimate interest is not outweighed by the data subject’s interests and fundamental rights and freedoms.

Data erasure and storage duration

The personal data of the data subject is erased, anonymised or blocked as soon as the purpose of the storage ceases to apply. In addition, storage may take place if required by European or national law in EU regulations, laws or other regulations to which AWI is subject. Blocking, anonymisation or deletion of the data also takes place if a storage period prescribed by the standards mentioned expires, unless there is a need for further storage of the data in order to conclude or fulfill the contract.

Rights of the data subject

As the data subject whose personal data is collected within the scope of the above-mentioned services, you have the following rights, unless any legal exceptions apply in individual cases:

  • Information (Art. 15 GDPR)
  • Rectification (Art. 16 GDPR)
  • Erasure (Art. 17 (1) GDPR)
  • Restriction of processing (Art. 18 GDPR)
  • Data portability (Art. 20 GDPR)
  • Objection to processing (Art. 21 GDPR)
  • Withdrawal of consent (Art. 7 (3) GDPR)
  • Right to lodge a complaint with a supervisory authority (Art. 77 GDPR). For AWI, this is the Landesbeauftragte für den Datenschutz und Informationssicherheit (State Data Protection and Freedom of Information Officer), Arndtstrasse 1, 27570 Bremerhaven.

Social media

Two clicks for more data protection

In order to protect our users’ privacy and data, we use the tried-and-tested two-click process, also known as the Shariff solution, for sharing content in social networks. The use of this process means that our websites are delivered with inactive buttons that do not transfer any data to social networks. Users can nonetheless manually activate the buttons, thereby creating a connection to their preferred network (first click). The second step involves the user then giving their recommendation (second click). Activating one of the buttons in the first step therefore means that the user consents to transmit data to the social network concerned for this one page and for the requested service.

Data protection regulations on the use of Twitter

We have integrated components of Twitter on some of our web pages. Twitter is a multilingual, publicly accessible micro-blogging service where users can publish and share so-called tweets, i.e. short messages limited to 280 characters. These short messages can be accessed by anyone, i.e. also by individuals not registered with Twitter. Twitter makes it possible to address a broader audience via hashtags, links or retweets.

Twitter is operated by Twitter, Inc., 1355 Market Street, Suite 900, San Francisco, CA 94103, USA.

Each time you access one of the individual web pages operated by us as the controller and on which a Twitter component is integrated, the browser of your IT system is automatically prompted by the Twitter component to download an image of the Twitter component from Twitter. Please see for more information on the Twitter timeline.

If you are logged into Twitter at the same time, Twitter recognizes – with each visit of our website on which the Twitter component is used – which specific sub-page of our website you visit. This information is collected by the Twitter component and assigned to your Twitter account by Twitter.

Twitter will in each case be notified via the Twitter component that you have visited our website, provided you are simultaneously logged into Twitter when accessing our website; this takes place irrespective of whether you click the Twitter component or not. If you do not agree to such transmission of information to Twitter, you can prevent it by logging out of your Twitter account prior to accessing our website.

Please see for the applicable data privacy policy of Twitter.
