Critically reading and evaluating claims made in the primary literature are vital skills for the future professional and personal lives of undergraduate students. However, the formal presentation of intricate content in primary research articles presents a challenge to inexperienced readers. During the fall 2020 semester, I introduced a Collaborative Annotation Project (CAP) into my online 400-level developmental neurobiology course to help students critically read eight research papers. During CAP, students used collaborative annotation software asynchronously to add clarifying comments, descriptions of and links to appropriate websites, and pose and answer questions on assigned papers. Student work was guided and assessed using a CAP grading rubric. Responses to anonymous surveys revealed students found CAP helpful for reading the primary literature and the rubric clarified expectations for the project. Here, I describe how I introduced, used, and assessed CAP in my online class, and I share the detailed CAP instructions and rubric.

Marine imaging has evolved from small, narrowly focussed applications to large-scale applications covering areas of several hundred square kilometers or time series covering observation periods of several months. The analysis and interpretation of the accumulating large volume of digital images or videos will continue to challenge the marine science community to keep this process efficient and effective. It is safe to say that any strategy will rely on some software platform supporting manual image and video annotation, either for a direct manual annotation-based analysis or for collecting training data to deploy a machine learning–based approach for (semi-)automatic annotation. This paper describes how computer-assisted manual full-frame image and video annotation is currently performed in marine science and how it can evolve to keep up with the increasing demand for image and video annotation and the growing volume of imaging data. As an example, observations are presented how the image and video annotation tool BIIGLE 2.0 has been used by an international community of more than one thousand users in the last 4 years. In addition, new features and tools are presented to show how BIIGLE 2.0 has evolved over the same time period: video annotation, support for large images in the gigapixel range, machine learning assisted image annotation, improved mobility and affordability, application instance federation and enhanced label tree collaboration. The observations indicate that, despite novel concepts and tools introduced by BIIGLE 2.0, full-frame image and video annotation is still mostly done in the same way as two decades ago, where single users annotated subsets of image collections or single video frames with limited computational support. We encourage researchers to review their protocols for education and annotation, making use of newer technologies and tools to improve the efficiency and effectivity of image and video annotation in marine science.

Collect, share, and distribute information about protein three-dimensional structures. It serves as a portal for the scientific community to learn about protein structures solved by SG centers, and also to contribute their expertise in annotating protein function. The premise of the TOPSAN project is that, no matter how much any individual knows about a particular protein, there are other members of the scientific community who know more about certain aspects of the same protein, and that the collective analyses from experts will be far more informative than any local group, let alone individual, could contribute. They believe that, if the members of the biological community are given the opportunity, authorship incentives, and an easy way to contribute their knowledge to the structure annotation, they would do so. Therefore, borrowing elements from successful, distributed, collaborative projects, such as Wikipedia (the free encyclopedia anyone can edit) and from other open source software development projects, TOPSAN will be a broad, collaborative effort to annotate protein structures, initially, those determined at the JCSG. They believe that the annotation of proteins solved by structural genomics consortia offers a unique opportunity to challenge the extant paradigm of how biological data is collected and distributed, and to connect structural genomics and structural biology to the entire biological research community. TOPSAN is designed to be scalable, modular and extensible. Furthermore, it is intended to be immediately useful in a simplistic way and will accommodate incremental improvements to functionality as usage becomes more sophisticated. Their annotation pages will offer the end user a combination of automatically generated as well as expert-curated annotations of protein structures. They will use available technology to increase the speed and granularity of the exchange of scientific ideas, and use incentive mechanisms that will encourage collaborative participation.

imagery has become one of the main data sources for investigating seascape spatial patterns. this is particularly true in deep-sea environments, which are only accessible with underwater vehicles. on the one hand, using collaborative web-based tools and machine learning algorithms, biological and geological features can now be massively annotated on 2d images with the support of experts. on the other hand, geomorphometrics such as slope or rugosity derived from 3d models built with structure from motion (sfm) methodology can then be used to answer spatial distribution questions. however, precise georeferencing of 2d annotations on 3d models has proven challenging for deep-sea images, due to a large mismatch between navigation obtained from underwater vehicles and the reprojected navigation computed in the process of 3d building. in addition, although 3d models can be directly annotated, the process becomes challenging due to the low resolution of textures and the large size of the models. in this article, we propose a streamlined, open-access processing pipeline to reproject 2d image annotations onto 3d models using ray tracing. using four underwater image data sets, we assessed the accuracy of annotation reprojection on 3d models and achieved successful georeferencing to centimetric accuracy. the combination of photogrammetric 3d models and accurate 2d annotations would allow the construction of a 3d representation of the landscape and could provide new insights into understanding species microdistribution and biotic interactions.the dataset contains 4 compressed volumes corresponding to the 4 study sites used in this study. each volume contains a 3d mesh (.ply), a 3d textured mesh (.obj, .mtl, and textures), an optical navigation file (.json) and the set of images used for the evaluation of reprojection accuracy. the files were generated using matisse 3d v1.4 3d reconstruction software. the dataset also contains a biiigle annotation report (.csv) correponding to fauna annotation.
