Former Deputy Oceanographer of the Navy to Speak

Science and technology have been an integral part of the Navy for the past 70 years.  The period from 1960 to the 1980s was an important time in the history of oceanography and underwater acoustics in the Navy.  Understanding the ocean and development of new sensing and observational technologies remain as important today as they did for many decades.  In his presentation titled, “The Ocean, the Navy ad challenging career and technical opportunities” former deputy Oceanographer of the Navy, Robert S. Winokur will discuss Navy careers and the opportunity to work on key real-world challenges.  Winokur also served as the Assistant Administrator of the National Environmental Satellite Service, National Oceanic and Atmospheric Administration (NOAA).

Winokur’s talk, scheduled for Thursday, October 6 at 5 PM in GLRC 202, will provide an opportunity to discuss how civilians support the Navy, the importance of oceanography and science and technology for future naval capabilities, and a perspective from a career that included underwater acoustics and naval oceanography, environmental satellites, and ocean policy.

With 47 years of federal service, Robert Winokur has provided testimony on a number of occasions on oceanographic ships, climate services, satellite and space programs, ocean observing systems and environmental data services to Senate and House subcommittees for the Navy and NOAA.

Winokur’s visit to campus is sponsored by the SENSE Enterprise, the Department of Mechanical Engineering – Engineering Mechanics, and the Great Lakes Research Center.

October 3 SENSE Seminar: Surviving a Great Lakes rip current

In the last few years, deaths in the Great Lakes as a result of dangerous nearshore currents (longshore currents, rip currents and structurally induced currents) have increased at an alarming rate, averaging 11 fatalities and 25 rescues per year.  Warmer temperatures, increased water levels and storm intensity, and more people at the beach have all contributed to this threat. Mr. Jamie Racklyeft has experienced a near fatal encounter with a Great Lakes rip current and will describe his personal experience and resulting motivation.

On Monday, October 3rd at 5 PM, Racklyeft will talk about his experience and effort to help others avoid the dangers associated with nearshore currents.  His talk, What it’s like to drown: Surviving a Great Lakes rip current, will be held in the East Reading room of the Van Pelt and Opie Library.

Jamie Racklyeft leads the new Great Lakes Water Safety Consortium with members from eight Great Lakes states and Ontario who partner to increase awareness and safety to end drownings in the Great Lakes.

 

Racklyeft is a Lake Michigan rip current survivor. Exhausted and hopelessly battling the relentless current and waves off Van’s Beach in Leland, Michigan in 2012, he knows he’s lucky to be alive. Since then, he has dedicated himself to helping people avoid, escape, and save others from dangerous currents by applying human-centered design thinking principles and communication strategies.

Currently a Communication Director at the University of Michigan’s Institute for Clinical & Health Research (MICHR), Racklyeft has been in the communication profession for more than 30 years, serving research, corporate, healthcare, non-profit, academic, and entrepreneurial fields. He now leads the new Great Lakes Water Safety Consortium, with members representing all eight Great Lake states and Ontario, working together to end drowning. Racklyeft earned a Master’s in Education from Wayne State University and a Bachelor’s in General Studies from the University of Michigan, focusing on communication, psychology, and art history.

Rachlyeft’s visit and talk is hosted by the SENSE Enterprise, the Department of Mechanical Engineering – Engineering Mechanics, and the Great lakes Research Center.

 

Seminar: The Enigmatic Biscayne Aquifer

IMG_18352Friday, July 10, 11 AM – Noon; GLRC 202

The Enigmatic Biscayne Aquifer

Michael Sukop, PhD, PG, CHg; Professor, Florida Climate Institute Executive Board Member and liaison to Southeast Florida Regional Climate Change Compact; Lead Principal Investigator South Florida Water, Sustainability, and Climate Project; Florida International University, Miami FL

Abstract:

The karstic Biscayne Aquifer is an eastward-thickening wedge of limestone that serves as a designated sole-source aquifer for 5.5 million people. Its karst is eogenetic (formed during early burial) and in many cases characterized by thick and laterally extensive zones of touching-vug porosity from burrowing shrimp. The vugs are commonly about 2 cm in diameter and the porosity is commonly 50% or more, leading to very high permeability. Given its importance, the Biscayne Aquifer may be the best-studied aquifer of such high permeability, but consistent values of its hydraulic conductivity (K) have been elusive.

Our work has approached this problem with numerous methods and over a broad range of scales, including

● detailed Lattice Boltzmann Models (LBM) at pore scale,
● LBM and laboratory measurements at core scale,
● high-resolution borehole scale geostatistical and flow modeling based on borehole images,
● borehole scale slug testing, and
● aquifer test meta-analysis

Results indicate that there are systematic variations of 5 orders of magnitude in typical maximum K values obtained from these different techniques. Naturally, some of this is due to real variations in the physical samples tested, but the method used is the principal source of variation.

Frequently overlooked limitations of laboratory permeability measurements of core samples truncate the distribution of core K values. Slug tests in appropriately-constructed wells are generally underdamped and appear to underestimate K in this aquifer (returning maximum results comparable to those of a sand aquifer), possibly due to the Darcian flow assumption that underlies the available analyses methods for such tests. Aquifer tests are difficult to conduct in this aquifer and are often inconclusive.

LBM applied at numerous scales tend to converge and agree with simple pipe flow expectations and specialized laboratory measurements on a 0.1 m diameter core. LBM K results at small scale are consistent with LBM K from 2.72 m3-volume scale explicit pore/solid aquifer models based on novel geostatistical extrapolation of borehole optical images.
