In early July, 2023, Kenna Rubin joined the faculty as associate dean for research. Rubin will be working to grow GSO\u2019s research portfolio and assist campus partners on research collaborations across the university\u2019s colleges, as well as at the state, federal and international levels.<\/p>\n The following article is an in-depth look at Rubin\u2019s own research, as it happened at sea, on a science cruise in the Pacific.<\/p>\n As an oceanographer, volcanologist, geochemist and environmental chemist, Rubin focuses on environmental impacts of submarine volcanism, and paleo records of sea level change from coral reef settings. Before coming to GSO, she was a faculty member at the University of Hawaii for 31 years, where her teaching has focused on environmental chemistry, geochemistry and volcanology. Rubin strongly believes that migrating ocean science to all digital workflows, persistent identifier tagging, complete metadata documentation, open access data sharing and rapid dissemination of information are keys to major advances in environmental and climate research conducted in the coming decades.<\/em><\/p>\n A novel made up entirely of correspondence has never been the standard format for prose narratives. But it\u2019s never disappeared either. Authors from Goethe to Stephen King have used letters to craft stories that range from yearning to scary.<\/p>\n Writing about the work of Kenna Rubin, the new associate dean at GSO, was not unlike this literary device. As this report\u2019s deadline neared, Rubin had limited internet access. So she replied to questions across time zones, across a continent even, whenever she had a few moments. <\/p>\n A comparison to the \u201cepistolary novel\u201d isn\u2019t misplaced given the epic context for Rubin\u2019s poor signal: she was at sea for more than 10 weeks this fall on International Ocean Discovery Expedition 389, dubbed \u201cDrowned Hawaiian Reefs.\u201d <\/p>\n As the catastrophic-sounding title suggests, Expedition 389 studied submerged coral reefs off Hawaii\u2019s Big Island. These reefs were once at sea level but, as Rubin explained, they \u201crafted downward with the rest of the island as it sinks under its own weight.\u201d <\/p>\n How does an island gain weight? Volcanic eruptions, it turns out, can be a landmass\u2019 version of \u201cbulking up.\u201d In this case, all that accumulated mass and time adds up to a weighty\u2014and revealing\u2014geological history. <\/p>\n Armed with a remote-controlled commercial seabed drill, Expedition 389 cored the Big Island\u2019s sunken reefs to \u201crecover info about a half-million years of past climate records, the rate of sinking, and coral reef responses to sea level change,\u201d Rubin explained. These stories from the seabed are \u201cvery difficult to obtain by any other means.\u201d<\/p>\n While much of the cruise\u2019s research is embargoed for a year, Rubin could speak in \u201cgeneralities\u201d about the project. For an expedition working with millennias\u2019 worth of oceanic history, generalities should suffice. <\/p>\n As one of three inorganic geochemists on the ship\u2019s science team, Rubin played a key role in analyzing coral samples. The drill trawled the seabed for these samples and, after coring, pulled them up in the form of rock cylinders. Sometimes these tubes of rock reached the ship broken. But intact specimens, Rubin noted, showed \u201cthe innards of the coral reefs.\u201d <\/p>\n These fossilized coral guts offered a richness of data to help \u201creconstruct\u2026past climate and environmental records from when the reefs grew,\u201d Rubin wrote. Different corals grow in different conditions, and Rubin said \u201cthings like water clarity, nutrient supply, wave action, and temperature\u201d all affect not only which types of corals thrive but also if reefs can form.<\/p>\n Using radiocarbon or Uranium-thorium geochronology, Rubin identified the samples. What kinds of coral were being recovered, and how old were they? As of this writing, Rubin was still on the expedition, but back on land she\u2019ll continue dating the coral, adding the results into her \u201congoing research into the effects of rapid sea level change on coral reef ecology and morphology,\u201d she explained. <\/p>\n \u201cI am very interested in periods of past rapid sea level change as an analog for the future,\u201d Rubin wrote. \u201cSpecifically, I look at how reefs change in response to sea level rise upticks lasting a few centuries, because this should provide clues about what the next few centuries have in store for tropical coastal communities who depend on coral reefs for the wide variety of ecosystem services they provide.\u201d<\/p>\n During our extended interview, Rubin occasionally emailed the equivalent of scenic postcards in the form of JPEGs or screen-captured tweets.<\/p>\n From a lay perspective it was hard to know exactly what to look for in Rubin\u2019s picture of a hard, crumbly column of off-white. But after reading her explanation of coral guts, it became more legible to this untrained eye. Changes in color and texture weren\u2019t outwardly dramatic, but they told a story thousands of years in the making. What kinds of coral survived? What reefs grew to the size of empires? What other organisms were denizens of these fascinating sprawls? <\/p>\n Rubin has been looking at coral reefs for 25 years. The reefs\u2019 past ecology and their relationship to sea level change has formed the nucleus of her research. <\/p>\n \u201cIronically, my work on reefs is near and dear to my heart, but not the thing I am MOST known for,\u201d Rubin wrote. \u201cRather, I am most recognized globally as an expert on volcanoes and volcanism.\u201d <\/p>\n The not-so-odd couple of volcanoes and reefs also points toward the marriage of oceanography and Earth sciences: \u201cMany marine geologists would not be able to function without significant understanding in both,\u201d Rubin said. <\/p>\n Her own intertwining path began with a bachelors in chemistry, followed by postgraduate studies culminating in an M.S. and Ph.D. at Scripps Institution of Oceanography. By then it was the mid-1980s, which Rubin noted as \u201ca time of rapid expansion in studies of the seabed.\u201d So she pivoted from seawater chemistry to the study of submarine volcanoes, employing chemistry, ocean science and volcanology in a blend uncommon for the period. <\/p>\n \u201cMy niche in the ocean sciences is on using deep submergence tools in innovative ways,\u201d Rubin said, a specialty that\u2019s involved 30 piloted submersible dives and \u201ca couple hundred more remotely operated dives.\u201d<\/p>\n The research cruises are thrilling, yes, but so is teaching. Rubin calls it a \u201cpassion,\u201d with her role of professor echoing her childhood curiosity: to instill an understanding and advocacy for the world we inhabit. <\/p>\n \u201cPersonally, I am most energized by projects that have both scientific and human dimensions,\u201d Rubin said, something she hopes to continue at GSO by \u201cdo[ing] research that is not only academically sound, but also directly helpful to ordinary citizens in their everyday lives.\u201d<\/p>\n One upcoming project involving GSO colleagues and students is a proposal for \u201ca deep submergence study\u2026of volcanism and hydrothermal activity\u201d which entails taking the ALVIN submersible at sites that are \u201cway deeper than the Titanic,\u201d Rubin said. Even the deepest depths need their story told. Unfortunately the most distant reaches of the sea can\u2019t write novels, letters or laments. Their story might be more easily told with pictures. Thankfully, those have gotten better, too. <\/p>\n Rubin said \u201creal-time, well-illuminated, well-geolocated 4K images [collected] miles below the sea surface\u201d now exist. Such resolution was unthinkable in the days of slide film and VHS tapes [when I started doing this.]\u201d For Rubin and researchers like her, these advances make our world more tangible. It\u2019s certainly something to write home about.<\/p>\n","protected":false},"excerpt":{"rendered":" Professor Kenna Rubin to Manage and Grow the Research Portfolio By Alexander Castro Editor’s Note In early July, 2023, Kenna Rubin joined the faculty as associate dean for research.

\u201cHere is a picture of a core showing various now-skeletal remains for reef organisms preserved in the column of rock,\u201d Rubin wrote about the attached picture.<\/p>\n
\nThe depths, apparently, are where it\u2019s at: \u201cThe vast majority of the seabed remains unmapped, uncharted and unseen by human eyes,\u201d Rubin wrote, adding that we know \u201cfar less\u201d about most of the Earth\u2019s surface crust and the seabed than we do Mars. <\/p>\n
