Pinniped censuses at Año Nuevo, California, 1967-2017

Richard Condit, Patricia Morris & Burney Le Boeuf
Regular pinniped censuses at Año Nuevo Island, California, were initiated by our research group in 1967 to support studies of reproductive behavior of male elephant seals, Mirounga angustirostris. Research on elephant seals at the colony has continued since, expanding to cover female behavior, reproductive success, physiology and energetics, migrations and foraging, and more. The other species of pinnipeds, Steller sea lion (Eumetopias jubata), California sea lion (Zalophus californianus), and harbor seal (Phoca vitulina), have been...

JAVA software for operating Alvin/Jason Heat Flow Probe

Andrew Fisher, Brecky Morris & Tess Weathers
The Alvin/Jason heat flow probe is operated from a PC (Windows or Mac) using a Java-based program that has a GUI for interaction with probe electronics. This software replaces C-based program that was delivered with the tools in 1996, communicating with the probe using a low-level command language, and allowing the user to monitor system performance during measurement. As described in this document, the system can be tested on the bench before deployment to assure...

Data from: Geographic structuring of Antarctic penguin populations

Jarrod Santora, Michelle LaRue & David Ainley
We hypothesized that regional spatial organization of Antarctic penguin breeding populations was affected by social factors, i.e., proximity and size of adjacent colonies, and by physical factors, i.e., availability of breeding habitat and proximity of polynyas and submarine canyons where prey is abundant. The hypothesis of Furness & Birkhead (1984), that forage competition and density-dependence affect geographic structure of seabird populations, was tested previously for Antarctic penguins when biologging to quantify colony foraging areas was...

Northern elephant seal UAS mass estimates

Roxanne Beltran
Unmanned aerial system (UAS) photogrammetry offers a method that is safer for both animals and researchers and is logistically simpler than traditional weighing methods (Fiori et al. 2017). Additionally, UAS photogrammetry facilitates larger sample sizes because it allows measurement at larger spatial scales, thereby increasing statistical power (Sweeney et al. 2015). However, UAS photogrammetry requires calibration and validation prior to use in order to assess the error relative to known mass measurements. Species-specific calibration of...

An escape theory model for directionally moving prey and an experimental test in juvenile Chinook salmon

Megan Sabal, Joseph Merz, Suzanne Alonzo & Eric Palkovacs
Prey evaluate risk and make decisions based on the balance between the costs of predation and those of engaging in antipredator behavior. Economic escape theory has been valuable in understanding responses of stationary prey under predation risk; however, current models are not applicable for directionally moving prey. Here we present an extension of existing escape theory that predicts how much predation risk is perceived by directionally moving prey. Perceived risk is measured by the extent...

A sample of Saturn interior density profiles derived with MCMC and gravity-based likelihood.

Naor Movshovitz, Jonathan Fortney, Chris Mankovich, Daniel Thorngren & Ravit Helled
We ran a Markov-Chain Monte Carlo algorithm to derive the posterior distribution of density profiles for Saturn, where the likelihood function was a chi-squared distributed distance of each curve's gravity coefficients from the values reported for that planet by the Cassini radio science team (Iess et al., 2019). The result is a large sample of interior profiles of Saturn consistent with observation and minimally constrained by model assumptions. This sample is archived here in sufficiently...

Cordillera Huayhuash Water Quality 2010-2011

Timothy Norris
The Cordillera Huayhuash is the second highest mountain range in the Peruvian Andes and is important for tourism, mining, and local livelihoods. These three economic activities all share an interest in the water quality of the over 50 lakes and associated drainages that exist in the region. Water quality monitoring can help ease tensions between interests from these distinct economic sectors. This dataset reports on two rounds of water quality sampling and testing performed at...

Ultrasound Investigation of Irish Palatalization (Phase 1, Connacht dialect)

Ryan Bennett, Grant McGuire, Máire Ní Chiosáin & Jaye Padgett
This dataset documents the production of palatalized and velarized consonants in Connemara Irish gathered in 2010 using a portable ultrasound device. Ultrasound imaging provides direct information about tongue body shape and movement, crucial to an understanding of palatalization and velarization. We also recorded video of lip movement, and audio, simultaneously with the ultrasound video. The shape of the tongue body, and of the lips, were extracted from video and averaged by statistical means. This dataset...
