Shifting ocean carbonate chemistry during the Eocene-Oligocene climate transition: implications for deep ocean Mg/Ca paleothermometry

first_imgTo date, no conclusive evidence has been identified for intermediate or deep water cooling associated with the > 1 parts per thousand benthic delta O-18 increase at the Eocene-Oligocene transition (EOT) when large permanent ice sheets first appeared on Antarctica. Interpretation of this isotopic shift as purely ice volume change necessitates bipolar glaciation in the early Oligocene approaching that of the Last Glacial Maximum. To test this hypothesis, it is necessary to have knowledge about deep water temperature, which previous studies have attempted to reconstruct using benthic foraminiferal Mg/Ca ratios. However, it appears likely that contemporaneous changes in ocean carbonate chemistry compromised the Mg/Ca temperature sensitivity of benthic foraminifera at deep sites. New geochemical proxy records from a relatively shallow core, ODP Site 1263 (estimated paleodepth of 2100 m on the Walvis Ridge), reveal that carbonate chemistry change across the EOT was not limited to deep sites but extended well above the lysocline, critically limiting our ability to obtain reliable estimates of deep-ocean cooling during that time. Benthic Li/Ca measurements, used as a proxy for [CO32-], suggest that [CO32-] increased by similar to 29 mu mol/kg at Site 1263 across the EOT and likely impacted benthic foraminiferal Mg/Ca. A [CO32-]-benthic Mg/Ca relationship is most apparent during the early EOT when the overall increase in [CO32-] is interrupted by an apparent dissolution event. Planktonic d18O and Mg/Ca records suggest no change in thermocline temperature and a delta O-18(seawater) increase of up to 0.6 parts per thousand at this site across the EOT, consistent with previous estimates and supporting the absence of extensive bipolar glaciation in the early Oligocene.last_img read more

New Web site aids job-seekers

first_imgAs the spring semester rapidly comes to a close and Notre Dame students anxiously await responses from companies in one of the highest unemployment environments in the decade, a new resource, Grads2Biz, can help promote their success with job and internship placement.Grads2Biz, which launched this month, works to connect top students from America’s elite schools and programs to Fortune 500 companies.It differentiates itself from other job boards online “by promoting students and recent grads instead of jobs listed by companies,” according to its April 1st press release.Students create personal profiles including information on their majors, employment or internship preference, clubs and memberships, and date of availability to begin work. Employers then search for talent using this variety of criteria.“This simple format gives employers easy access to the resumes of students whose profiles fit their needs, and frees students from the tedium of completing numerous applications and composing repetitive cover letters,” the press release said.The job board was initiated by 21-year-old Alexander Mayer, a current student at the University of Wisconsin and a first-time entrepreneur.“Grads2Biz strives to make the employment process as quick and painless as possible on both sides of the equation, employer and job seeker,” Mayer said in the release. “Our unique process helps elite talent find elite businesses nearly effortlessly.”The new business can help Notre Dame students specifically, Grads2Biz representative Melissa Russell said.“With Grads2Biz, Notre Dame students stand out from the crowds and don’t get lost in the shuffle. There’s a lot of noise out there that can make it hard for employers to find you,” she said.She identified Grads2Biz as a strong resource for students in the nation’s current economic climate.“Sending in your resume isn’t a guarantee that it will even get read anymore, especially with the job market being so saturated,” she said. “But there is a definite and real value in bringing the best and the brightest to the top, so that these top employers can find the right college students and graduates for these awesome entry-level jobs or internships.”Students eligible to use the resource are those attending the specific institutions identified by the company with a minimum grade point average of 3.2.“We think so highly of Notre Dame students, and know that employers do too, so when we launched we made sure we were admitting them to the site right away,” Russell said.Grads2Biz also provides job hunting and career advice for students, and will soon feature a resource guide and blog “to give tips on how to best traverse a rough job market,” the press release announced.“Connecting students to their dream jobs is our ultimate goal, but we also want them to be prepared to be successful in whatever they do,” Mayer said in the press release.Russell said opportunities exist for underclassmen already considering the opportunities that await them upon graduation. “We’re also looking for creative, enthusiastic individuals to become student ambassadors from Notre Dame,” she said.Students using the resource pay fifty dollars for a three year membership, according to the website. To celebrate its launch, however, the company has made registration free for students into the summer.last_img read more

PTTEP Australasia names new CEO

first_imgThai oil company PTTEP has named new CEO for its Australian business PTTEP Australasia.Ryan Hartfield is the new CEO of PTTEP AAPTTEP said Thursday that Ryan Hartfield, former Head of Contracts and Procurement at PTTEP Australasia, would take over as new Chief Executive Officer in Australia.“I’m excited to have the opportunity to drive forward PTTEP’s business in Australia as we begin a new chapter,” Hartfield said.Before joining PTTEP AA in 2012, Hartfield worked for Mubadala Development Company in Abu Dhabi, and Woodside.PTTEP Australasia was the operator of the Montara platform in the Timor Sea offshore W. Australia, which exploded and spilled oil into the ocean in 2009. PTTEP was in 2012 fined 510.000 Australian Dollars in the Northern Territory Magistrate’s Court over the Montara incident.The company sold the Montara oil field to Jadestone Energy in July 2018, and transfer of operatorship was completed in August 2019.While no longer having an interest in the Montara field, PTTEP Australasia might still be affected by it. Namely, the company has recently been sued by Indonesian seaweed farmers whose livelihoods have allegedly been destroyed after the 2009 blowout and subsequent oil spill.Also worth reminding, Indonesia in 2017 filed a $2 billion lawsuit against PTTEP for the Montara oil spill saying PTTEP had not shown good faith in resolving problems with Montara oil pollution that reached the area of ​​the East Nusa Tenggara province.PTTEP has claimed that no oil from Montara reached the shores of Indonesia and that no long-term damage was done to the environment in the Timor Sea.Having sold the Montara asset, PTTEP AA currently operates the Cash Maple gas and condensate field, as well as several other permits in the Timor Sea.Offshore Energy Today StaffSpotted a typo?
