Aloha fellow marine mammal researchers! I wanted to take a quick moment and make sure you were all aware of the upcoming 7th International Bio-Logging Symposium scheduled for October 2021. We would really appreciate seeing a good representation of marine mammal bio-logging research and hope you will consider submitting an abstract and joining us (virtually) in October. The 7th International (and 1st virtual) Bio-logging Symposium (BLS7) is scheduled for 18-22 October, 2021. Bio-logging allows researchers to gain insight into the movement, behavior, and environments of animals through the use of electronic tags. Bio-logging is revolutionizing the field of biology and helping to advance global efforts to understand our planet and conserve biodiversity. The International Bio-Logging Society brings together researchers from around the world who are interested in bio-logging methods and the scientific insights they provide. The society’s membership includes biologists, conservation practitioners, physicists, engineers, computer specialists, and mathematicians. By encouraging interdisciplinary exchange and collaboration, the Society hopes to advance the scientific understanding and lasting protection of global biodiversity. The first International Bio-Logging Science Symposium took place 17 years ago in Japan. Since then, a growing group of interdisciplinary researchers have gathered together at symposia in Germany, France, Australia, the USA, and Scotland to pioneer advances in animal telemetry. We would like to welcome you to join us for the 7th International Biologging Science Symposium. BLS7 aims to facilitate sharing of cutting edge bio-logging science across a broad range of taxa and disciplines. We look forward to hearing about all of the advancements in bio-logging tools, approaches, and analysis techniques in October and are hoping for this to be the most inclusive and expansive representation of bio-logging science yet. The theme for the symposium is “Tracking the Changing World Around Us” and will be broadcast across the planet from Honolulu, Hawaii. The scheduled program will have featured oral presentations, keynote discussions, electronic posters, and speed talks. In addition, we have plans for social interactions, small group and networking events, concerts, virtual exhibit/sponsor booths, and much more. In fact, the amount of content we’re planning for can’t possibly fit into 5 days. So, all registrants will have access to content on-demand for up to 6 months! Abstract submissions are now open <https://www.bls7hawaii.com/abstracts> and we would like you to consider submitting before the deadline on 16 May 2021. Registration costs will be $150 for professionals and $50 for students with additional discounts for those from traditionally lower funded countries and for early registration. Registration will open on May 10 with early-bird registration discounts available until July 1. Registration after October 1 will increase to $175 for professionals and $75 for students. Please visit our website at www.bls7hawaii.com, follow the International Bio-Logging Society on Twitter (@biologging), and spread the word far and wide to anyone you think might be interested in joining us. -- *Josh M.
