Dear Colleagues,

Estuarine and coastal ecosystems are dynamic and complex environments that play a crucial role in the ecological balance of our planet. As these regions undergo rapid changes due to anthropogenic and natural factors, there is an increasing need for advanced monitoring techniques to understand and manage their intricate dynamics. Remote sensing, with its ability to capture large-scale spatial and temporal information, has emerged as a powerful tool in studying estuarine and coastal waters. However, the efficacy of remote sensing algorithms relies heavily on accurate and comprehensive in situ data for calibration and validation.

This Special Issue, entitled “Applications of In-Situ Research for Remote Sensing Algorithms in Estuarine and Coastal Waters”, will address the relationship between surveys performed directly in the aquatic environment and remote sensing methodologies. This collection of articles aims to highlight the key role of in situ data in improving the accuracy and reliability of remote sensing algorithms applied in estuarine and coastal environments.

We invite you to publish the results of in situ studies conducted with a variety of instruments (such as fluorometers, spectrophotometers, turbidity sensors, or acoustic Doppler profilers) that can contribute to improving algorithms for data acquisition from various remote sensing techniques (ocean color sensing, lidar, synthetic aperture radar, multispectral and hyperspectral imaging, thermal imaging, and others).

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
