New record of Frilled shark Chlamydoselachus anguineus Garman, 1884 (Chondrichthyes: Hexanchiformes) in the South Pacific Ocean by Maria J. Indurain, Angel Mancilla, Leandro Brizuela, Carolina Vargas-Caro, Carlos Bustamante

“…The global number of records for these sharks does not exceed 40, with most sightings reported in the Western Pacific Ocean. In 1976, one specimen was recorded for the first time in the South East Pacific Ocean; however, this study provides new evidence for the presence of Chlamydoselachus anguineus in Chilean waters, extending its distribution range 850 km south of the previous record. …”

Determination of distance away and depth of transmitters relative to a vertical acoustic telemetry array in the open ocean by Eric V. C. Schneider, Brendan S. Talwar, David M. Bailey, Shaun S. Killen, Dale M. Webber, Courtney E. MacSween, Travis E. Van Leeuwen, Frank I. Smith

“…Acoustic telemetry can provide high resolution positioning data for tagged animals within an array of receivers with overlapping fields of detection; however, this technique has not been applied in deep open-ocean environments off the benthos. Results Herein, we detail the development of a novel vertical acoustic telemetry array that can be mounted on, or suspended from, various moored and free-floating structures in the open ocean, thus facilitating high resolution tracking of structure-associated epipelagic animals. …”

Leveraging the CYGNSS Spaceborne GNSS‐R Observations to Detect Ionospheric Irregularities Over the Oceans: Method and Verification by Xiaodong Ren, Hang Liu, Dengkui Mei, Pengxin Yang, Zhiyu Zhang, Mohamed Freeshah, Xiaohong Zhang

“…All comparisons and validations conducted within this study illustrate that the spaceborne GNSS‐R measurements provide complementary data and realize the timely observation as well as confirmation of the ionospheric irregularities at the same location over the oceans. It is expected to benefit the application of spaceborne GNSS‐R in ionospheric irregularities monitoring and applications over the ocean area.…”

Reconstructing the experienced temperature during the larval oceanic migration of anguillid eels from otolith stable oxygen isotopes by Mari Kuroki, Shunsuke Hayasaka, Kozue Nishida, Toyoho Ishimura, Akihiro Okamura, Yoshiaki Yamada, Yu-San Han, Kotaro Shirai

“…Abstract Migration routes and the depth patterns of anguillid eel larvae migrating long distances from spawning grounds in the ocean remain poorly understood. We used otolith stable isotope analysis to study the oceanic migrations of anguillid eels by reconstructing experienced water temperature histories of larvae. …”

Radar Characterization of Salt Layers in Europa's Ice Shell as a Window Into Critical Ice‐Ocean Exchange Processes by N. S. Wolfenbarger, D. D. Blankenship, D. A. Young, K. M. Scanlan, C. J. Chivers, D. Findlay, G. B. Steinbrügge, K. Chan, C. Grima, K. M. Soderlund, D. M. Schroeder

“…We demonstrate how ice‐penetrating radar measurements of salt layer thickness could establish lower bounds on the parameter space of possible initial reservoir thickness and salinity, constrain the origin of reservoirs (ice shell melt vs. ocean injection), and—if sourced through ocean injection—the ocean salinity.…”
