Despite being an East Coast native, I felt an unmistakable draw to Oregon. Everything I saw during that morning\u2019s hike, from the misty fog that enshrouded evergreens and the ocean with mystery, to the giant banana slugs, felt at once foreign and a place I could call home. Out of all the places I visited along that Pacific Coast road trip, Oregon left the biggest impression on me.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><a href=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo1-1.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo1-1-1024x768.jpg\" alt=\"\" class=\"wp-image-4148\" width=\"568\" height=\"425\" srcset=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo1-1-1024x768.jpg 1024w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo1-1-300x225.jpg 300w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo1-1-768x576.jpg 768w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo1-1.jpg 1440w\" sizes=\"auto, (max-width: 568px) 100vw, 568px\" \/><\/a><figcaption>Figure 1.

Surface interval events for oxygen replenishment and rest are a vital part of baleen whale feeding ecology, as it provides a recovery period before they perform their next foraging dive (Hazen et al., 2015; Roos et al., 2016). Despite spending so much time studying the importance of resting periods for mammals, that 2016 road trip was my last true extended resting period\/vacation until, several years later in 2021, I took another road trip. This time it was across the country to move to the place that had enraptured me.<\/p>\n\n\n\n<p>Now that I am settled in Corvallis, I have reflected on my journey to grad school and my recent road trip; both prepared me for a challenging and exciting new chapter as an incoming MSc student within the Marine Mammal Institute (MMI).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Part 1: Journey to Grad School<\/strong><\/h3>\n\n\n\n<p>When I took that photo at the Cape Perpetua Overlook in 2016, I had just finished the first two semesters of my undergraduate degree at UNC Chapel Hill. As a first-generation, non-traditional student those were intense semesters as I made the transition from a working professional to full-time undergrad.<\/p>\n\n\n\n<p>By the end of my freshman year I was debating exactly what to declare as my major, when one of my marine science TA\u2019s, Colleen, (who is now <a href=\"https:\/\/colleenbove.science\/\">Dr. Bove<\/a>!), advised that I \u201ccollect experiences, not degrees.\u201d I wrote this advice down in my day planner and have never forgotten it. Of course, obtaining a degree is important, but it is the experiences you have that help lead you in the right direction.<\/p>\n\n\n\n<p>That advice was one of the many reasons I decided to participate in the Morehead City Field Site program, where UNC undergraduates spend a semester at the coast, living on the Duke Marine Lab\u2019s campus in Beaufort, NC. During that semester, students take classes to fulfill a marine science minor while participating in hands-on research, including an honors thesis project. The experience of designing, carrying out, and defending my own project affirmed that graduate school in the marine sciences was right for me. As I move into my first graduate TA position this fall, I hope to pay forward that encouragement to other undergraduates who are making decisions about their own future path.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large is-resized\"><a href=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo3.png\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo3.png\" alt=\"\" class=\"wp-image-4149\" width=\"503\" height=\"283\" srcset=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo3.png 927w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo3-300x169.png 300w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo3-768x432.png 768w\" sizes=\"auto, (max-width: 503px) 100vw, 503px\" \/><\/a><figcaption>Figure 2.

I was solo for much of the drive, which meant there was no one to argue when I decided to binge listen to podcasts. My new favorite is <a href=\"https:\/\/open.spotify.com\/show\/1KzrasExlM5dgMYwgFHns6\">How To Save A Planet<\/a>, hosted by marine biologist Dr. Ayana Elizabeth Johnson and Alex Blumberg.

My mammal research experience included analyzing drone imagery, behind a computer, that had already been captured.

I will be learning the ropes from <a href=\"https:\/\/mmi.oregonstate.edu\/people\/lisa-hildebrand\">Lisa Hildebrand<\/a> and soaking up as much information as possible as I will be taking over as lead for this project next year.<\/p>\n\n\n\n<p>It will take some time before my master\u2019s thesis is fully developed, but it will likely focus on assessing the environmental factors that influence gray whale zooplankton prey availability, and the subsequent impacts on whale movements and health. For five years, the Port Orford project has conducted GoPro drops at 12 sampling stations to collect data on zooplankton relative abundance.<\/p>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-image\"><figure class=\"aligncenter is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo56.png\" alt=\"\" class=\"wp-image-4152\" width=\"192\" height=\"367\" srcset=\"https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo56.png 295w, https:\/\/osu-wams-blogs-uploads.s3.amazonaws.com\/blogs.dir\/2115\/files\/2021\/07\/photo56-157x300.png 157w\" sizes=\"auto, (max-width: 192px) 100vw, 192px\" \/><\/figure><\/div>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"660\" height=\"372\" src=\"https:\/\/www.youtube.com\/embed\/lOpoBP1Mhuw?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span>\n<\/div><figcaption>Figures 5 &amp; 6.

According to <a href=\"https:\/\/www.iucn.org\/sites\/dev\/files\/ocean_deoxygenation_issues_brief_-_final.pdf\">the IUCN\u2019s 2019 Issues Brief<\/a>, these factors have resulted in an oxygen decline of 2% since the middle of the 20th century, with most of this loss occurring within the first 1000 meters of the ocean. Two percent may not seem like much, but many species have a narrow oxygen threshold and, like pH changes in coral reef systems, even slight changes in DO can have an impact. Additionally, the first 1000 meters of the ocean contains the greatest amount of species richness and biodiversity.<\/p>\n\n\n\n<p>Previous research done in a variety of systems (i.e., estuarine, marine, and freshwater lakes) shows that dissolved oxygen concentrations can have an impact on predator-prey interactions, where low dissolved oxygen results in decreased predation (Abrahams et al., 2007; Breitburg et al., 1997; Domenici et al., 2007; Kramer et al., 1987); and changes in DO also change prey vertical distributions (Decker et al., 2004). In Port Orford, we are interested in understanding the interplay of factors driving zooplankton community distribution and abundance while investigating the trophic interaction between gray whales and their prey.<\/p>\n\n\n\n<p>I have spent some time with our new DO sensor and am looking forward to its first deployments in Port Orford!
