RockEDU summer students Priyam Shah and Michael Epelman, who just completed high school, teamed with mentor extraordinaire Mark Stoeckle to study the fishes of an NYC Superfund Site, Newtown Creek. Their excellent poster shows that eDNA detected a surprising diversity of fish in Newtown Creek, despite ongoing pollution and sewage overflow. The number and relative abundance of fish species differed among sites consistent with species habitat preference and pollution tolerance. Our data support eDNA as a cost-effective, non-destructive method for monitoring fish populations and assessing habitat restoration efforts in Newtown Creek and other Superfund sites
IQOE Newsletter #11 reports on the IQOE Science Committee meeting and Global Library on Underwater Sounds (GLUBS) workshop in Woods Hole in April in which Jesse participated, as well as the first World Ocean Passive Acoustic Monitoring Day in June. The newsletter also provides updates on the global hydrophone metadatabase, low-cost hydrophones, and effects of the COVID-19 pandemic on ocean sound.
A stalwart member of the International Scientific Steering Committee of the Census of Marine Life, Vera Alexander passed away at the age of 90 in Fairbanks AK in May. The Arctic Research Consortium US earlier offered this informative tribute.
Jesse worked closely with Vera during the Census of Marine Life from 1999-2010 and offers this remembrance of The Many Contributions of Vera Alexander.
A child of the International Quiet Ocean Experiment, today is the first World Ocean Passive Acoustics Monitoring (WOPAM) day. The IQOE leaders, including Miles Parsons and Steve Simpson, have prepared two very cool 90-second videos to initiate WOPAM day.

For a 50th Harvard College Reunion Seminar on EO Wilson’s proposal to conserve half Earth, Jesse Ausubel and Mark Stoeckle, assisted by Elizabeth Munnell, conducted a survey of vertebrates in three locations in the Charles River and two in Boston Harbor. The 14 slides on The Charles River and Boston Harbor Then and Now tell a story of remarkable ecological recovery.

Mark Stoeckle and Jesse Ausubel presented in the NOAA ‘Omics Seminar Series on Marine fish eDNA Metabarcoding: Promising Developments and Early Applications. The outline:
–eDNA abundance matters (relevant to detection, quantification, field design, laboratory protocols)
–Adding internal standard to metabarcoding PCRs quantifies eDNA (converts relative sequence reads to absolute eDNA copies)
–Current marine fish metabarcoding protocols ready for wider use (reasonably accurate index of fish abundance, especially for more abundant species)
–eDNA metabarcoding can overcome information hurdles for ecosystem-based management
