Record Eclipse Shadow Bands at the August 12, 2026 Eclipse

During the few moments before and after totality, rippling patterns called shadow bands race across the ground. This citizen science project invites eclipse observers across Iceland and Spain to record shadow bands and help answer questions that remain largely unexplored Why Participate? • Witness one of nature’s rarest optical phenomena. • Contribute to genuine scientific research. • Help answer questions about how location and altitude influence shadow bands. • Be part of an international citizen science effort. • Receive detailed observing instructions before the eclipse. We're Looking for Volunteers • Locations near the eclipse centerline in Iceland or Spain. • Locations near the edge of totality in Iceland or Spain. • High-altitude observation sites in Iceland or Spain. • If you're already planning to travel to Iceland or Spain for the eclipse, your observations could be especially valuable.

From Citizens to Science: Tools Driving Climate Action

On April 28, 2025, during the European Geosciences Union (EGU) in Vienna, the H2020 I-CHANGE project will hold its final scientific event titled “From Citizens to Science: Tools Driving Climate Action” Over the past four year, I-CHANGE has worked to place citizens at the core of climate action, demonstrating that informed, empowered communities are essential for achieving behavioural change. By combining active citizen participation, innovative technologies, and scientific collaboration, the project has fostered behavioural transformations towards more sustainable living. This closing event will present the outcomes of I-CHANGE, showcasing results from its eight Living Labs across Europe and beyond. These Living Labs served as active hubs for environmental monitoring, and community engagement, emphasizing how citizens can observe and reduce their own environmental impacts. The event will feature the presentation of the project’s final results, including scientific findings, technological and engaging activities that have been implemented to raise climate change awareness and foster participatory science. It will also include talks from sister projects involved in citizen science initiatives related to climate change, and offer reflections on how citizen-generated data can complement scientific observations and help shape a more sustainable future. In addition, on May 1, 2025, key I-CHANGE results will be featured during the EGU session titled “Engaging Citizens in Understanding Urban Climate and Climate Change Risks through Participatory Science.” This session invites contributions that explore citizen participation, crowdsourced data collection, and effective practices for integrating the public into climate adaptation efforts across Europe.

BIO-DATAthon: A unique validation event of biodiversity data!

The activity aims to validate species names of the biodiversity observations coming from several citizen science platforms, such as Natusfera, Pl@ntNet or Artportalen; you can validate terrestrial or marine images, depending on your expertise! The event is organised by the Cos4Cloud project. Natusfera and Artportalen are citizen science platforms where volunteers update and identify all kinds of biodiversity images, while Pl@ntNet gathers plants’ observations worldwide. These images are now available in Cos4Bio, a new online platform that integrates observations on biodiversity from various citizen science platforms. When? This online event will take place from the 7th of December until the 15th of January; you can do it from home when it fits you better; no pressure! Who is this event for? It is aimed at experts (by learning or by experience) who can identify species names (any taxon!). Read more on Cos4Bio and the event at the event page.

Cos4Cloud and its services for the citizen science community

Cos4Cloud is a EU-funded project that is co-designing, prototyping and implementing a number of new tools and services that address the technological challenges shared by citizen observatories. These services can help citizen observatories to improve data and information quality of observations and can be used as modules, so that any existing citizen science observatory will be able to choose and install the technological services they wish. In this webinar, we will give a short introduction of the project and present two of the services developed: MOBIS and FASTCAT-Cloud. MOBIS is a service to create integrative citizen science apps where you can report all your environmental and biodiversity observations in one Android or iOS app. FASTCAT (Flexible Ai System for CAmera Traps)-Cloud is an open website service that allows you to automatically filter out most unwanted pictures and video streams, keeping images of animals, and to integrate machine learning technology, among other things. The presentations will be followed by a Q&A with speakers. The webinar will last one hour. After closing the webinar we will keep the Zoom channel open for participants to ask further questions and make suggestions about how Cos4Cloud can benefit their citizen science project(s).

Citizen Science for the Oceans: From observation to information - towards digital twins of the ocean

In this webinar you will learn about citizen science activities related to the oceans. We will use the case of jelly fish as an example, start with the observations done by citizens using mobile apps. Then you learn how the data can be integrated in systems, including the use of standards making the data, in this case biological data, interoperable. You will also learn how to approach making the apps themselves. As NextGEOSS already has citizen science data catalogued on the data hub, you will now learn how we will expand this with the help from among others Earthwatch through their contribution to the ILIAD project. This webinar aims to reach Earth observation professionals and students, Citizen science public and private organisations, App makers, ocean advocates, marine environmentalist, oceanographers, ecologists.

EuroBioBlitz 2021

Nature is vitally important, and nature is in trouble, but we can all help with nature’s recovery by helping fill in the gaps in what we know about the species on our doorsteps. By looking out for wildlife in your own neighbourhood, you can support vital conservation research whilst connecting with nature and enjoying the outdoors. That is why this September, researchers, school groups, citizens and wildlife enthusiasts across the continent are coming together in a race against the clock to put nature on the map, submitting photos and observations of wildlife in their neighbourhoods through the free, easy to use iNaturalist mobile phone app. Join an epic race for wildlife this September as citizens across Europe take part in the worlds’ first 48 hour continental BioBlitz!

NASA GLOBE Observer Mosquito Habitat Photo Challenge

The Global Learning and Observations to Benefit the Environment (GLOBE) Program invites citizen scientists from around the world to participate in the Mosquito Habitat Photo Challenge. This challenge combines Mosquito Habitat Mapper and Land Cover (two GLOBE Observer app tools) to document mosquito breeding habitats with photos. GLOBE would like you to take photos of mosquito habitats, in either natural or artificial containers. If mosquito larvae are present, you are encouraged to photograph them with a magnifier (optional). Then, we’d like you to take photos of the land around the habitat location using the Land Cover tool. Photos submitted during this challenge will be used to create automated classification programs that can identify mosquito larvae and the environments they prefer. Such computer programs can help prevent outbreaks of mosquito-borne disease

BioMARAtó

From the 1st of June until the 30th of September, the provinces of Barcelona, ​​Girona, and Tarragona will participate in a Bioblitz called "BioMARató". The region that gets the most underwater observations, detects more invasive and rare species or gets the most participants will win. This event is part of the City Nature Challenge (CNC), an international friendly competition of naturalistic observations where cities worldwide will compete with each other. Participate on your own or sign up for one of the free activities on the Catalan coast (beaches in the Barcelona Metropolitan Area, Costa Daurada, and Costa Brava)
