Journey North - Gray Whale observations by volunteer community scientists across the Eastern Pacific Ocean (1997-2020)
This data package contains Gray Whale migration data consisting of 1,546 total observational reports from 1997 - 2020 across the Eastern Pacific Ocean. These data were collected by 163 community scientists for Journey North, a crowdsourced participatory science program of the University of Wisconsin-Madison Arboretum. The Journey North Gray Whale Project is a study of Gray Whale phenology conducted at broad spatial and temporal scales. Since 1997, community scientists have tracked the migration of Gray Whales (Eschrichtius robustus) through the Eastern Pacific Ocean. Observers also provide estimates of the number of whales sighted. However, observers do not follow standardized methods for counting species observed. Observers do not observe at set times of the day, do not repeat observations regularly, and are not required to provide the length of time during which a specified number of species observed were counted. Therefore, it is recommended that this dataset be analyzed to indicate presence not abundance. Researchers are encouraged to read the rich information provided by volunteers in their comments. These comments provide qualitative information about observational reports. Researchers are also encouraged to refer to submitted photographs that also provide context for observational reports. The Journey North Gray Whale Project dataset is hosted by the University of Wisconsin-Madison Shared Web Hosting Service.

The former is our model in the Müller et al. (2019) reference frame, and the latter is our model implemented into the Shephard et al. (2013) plate reconstruction. Both of these folders contain the same types of files: coastlines, plate boundaries, plate topologies, a rotation file and terrane shapefiles.</p> <p>To view the models, open GPlates (downloadable at: <a href="https://www.gplates.org">www.gplates.org</a>), click 'File' > 'Open Project', navigate to the folder containing the desired model, and then click on the file <strong>Clennett_etal_2020_G3_XXXX.gproj</strong>. This will simultaneously open all the files that comprise the model. A layers panel will appear, with the option to turn on/off certain files. The view can be changed by clicking on the globe, and the model can be run by clicking the play button in the animation bar, starting from 170Ma. Features can be inspected by clicking the 'choose feature' tab, selecting a feature, and clicking 'query feature'.</p> <p>The files that comprise the model are described below:</p> <p>1. <strong>Clennett_etal_2020_Coastlines.gpml</strong>: Coastlines used in the reconstruction. The coastlines of western North America and Mexico were edited from the global model to account for later terrane accretions. </p> <p>2. <strong>Clennett_etal_2020_NAm_bounds.gpml</strong>: File containing the new plate boundaries digitised in this study.</p> <p>3. <strong>Clennett_etal_2020_Plates.gpml</strong>: File containing the edited plate boundaries of the global model, as well as our new continuously-closing plate topologies.</p> <p>4. <strong>Clennett_etal_2020_Rotations.rot</strong>: This is the rotation file that contains the relative motions between plates, terranes and plate boundaries for western North America and the eastern Pacific basin.

Temperature Profiles from the Eastern Tropical Pacific (0-300m) from January-February 2023
<p>Vertical temperature profiles taken as part of a research expedition to Clipperton Atoll. Water column temperature profiles were measured down to 300m depth by deploying a <em>RBRduet<sup>3</sup> T.D.</em> sensor<sup> </sup>(Range -5°C to 35°C; Initial accuracy ±0.002°C; Resolution <0.00005°C; time constant <1s). Data (downcast and upcast) is averaged by depth into 1 meter bins, and the standard deviation and number of measurements in each bin are included as columns in the data.</p> <p> </p> <p>This data is supplemented locally for the shallow waters of Clipperton Atoll with 21 water column profiles measured using a Mares Puck Pro dive computer (Range: -10 °C to +50 °C; Resolution: 1°C; Accuracy: ± 2 °C) worn by one of the expedition divers.</p>

Data from: New cranial fossils of the Jurassic turtle Neusticemys neuquina and phylogenetic relationships of the only thalassochelydian known from the Eastern Pacific
Neusticemys neuquina is a turtle from the Upper Jurassic of the Neuquén Basin, Patagonia, Argentina. Here we describe in detail a new skull, lower jaw, and a vertebra, utilizing both traditional anatomical description and computed tomography (CT). New diagnostic cranial characters of Ne. neuquina are: a round depression on the ventral surface of the basisphenoid, a relatively larger oval foramen nervi trigemini and reduced and steepened triturating surfaces on both the maxilla and dentary. The new morphological information presented in this study was included in a phylogenetic analysis, the primary result of which was recovery of Ne. neuquina within Thalassochelydia. Characters recognized as synapomorphies of this clade include (1) anterolateral recess of the anterior surface of the quadrate positioned lateral to the processus trochlearis oticum, (2) presence of a fossa on the supraoccipital-opisthotic-exoccipital contact area, (3) foramina anterius caroticus cerebralis located close together but independently perforating the basisphenoid, and (4) presence of the splenial in the mandible. Two contrasting dispersal scenarios may explain how this species of Thalassochelydia can be found outside of Europe. The presence of Ne. neuquina in the Neuquén Basin could be the consequence of an early dispersion event, for which we lack intermediate forms, or it may be the result of a later event once the clade was already established in Europe.
