Abstract
The Hudson River (HR) Estuary has a long history of pollution with a variety of contaminants including PCBs, and dioxins. In fact, 200 miles of the mainstem HR is designated a U.S. federal Superfund site, the largest in the nation, because of PCB contamination. The tidal HR hosts the southernmost spawning population of Atlantic tomcod, and studies revealed a correlation between exposure of juveniles to warm water temperature during summer to abundance of spawning adults of the same cohort in the following winter. Further, a battery of mechanistically linked biomarkers, ranging from the molecular to the population levels, were significantly impacted from contaminant exposures of the HR tomcod population. In response to xenobiotic insult, the HR tomcod population developed resistance to PCB sand TCDD toxicity resulting from a deletion in the aryl hydrocarbon receptor2 (AHR2) gene. Furthermore, RNA-Seq analysis of global gene expression demonstrated that effects of the AHR2 polymorphism were far more pervasive than anticipated. The most highly PCB-contaminated sediments in the upper HR were dredged between 2009 and 2015 with the objective of lowering PCB concentrations in fishes in the lower HR. Success of the remediation project has been controversial. These observations suggest that tomcod provides an informative model to evaluate the efficacy of HR PCB remediation efforts on downriver fish populations and possible interactive effects between contaminant exposure and a warming environment.

Abstract
Climate change is impacting ecosystems worldwide. Estuaries are diverse and important aquatic ecosystems; and yet until now we have lacked information on the response of estuaries to climate change. Here we present data from a twelve-year monitoring program, involving 6200 observations of 166 estuaries along >1100 kilometres of the Australian coastline encompassing all estuary morphologies. Estuary temperatures increased by 2.16 °C on average over 12 years, at a rate of 0.2 °C year-1, with waters acidifying at a rate of 0.09 pH units and freshening at 0.086 PSU year-1. The response of estuaries to climate change is dependent on their morphology. Lagoons and rivers are warming and acidifying at the fastest rate because of shallow average depths and limited oceanic exchange. The changes measured are an order of magnitude faster than predicted by global ocean and atmospheric models, indicating that existing global models may not be useful to predict change in estuaries.

Abstract
Anticipated future increases in air temperature and regionally variable changes in precipitation will have direct and cascading effects on U.S. water quality. In this paper, and a companion paper by Coffey et al. (2019), we review technical literature addressing the responses of different water quality attributes to historical and potential future changes in air temperature and precipitation. The goal is to document how different attributes of water quality are sensitive to these drivers, to characterize future risk to inform management responses and to identify research needs to fill gaps in our understanding. Here we focus on potential changes in streamflow, water temperature, and salt water intrusion (SWI). Projected changes in the volume and timing of streamflow vary regionally, with general increases in northern and eastern regions of the U.S., and decreases in the southern Plains, interior Southwest and parts of the Southeast. Water temperatures have increased throughout the U.S. and are expected to continue to increase in the future, with the greatest changes in locations where high summer air temperatures occur together with low streamflow volumes. In coastal areas, especially the mid-Atlantic and Gulf coasts, SWI to rivers and aquifers could be exacerbated by sea level rise, storm surges, and altered freshwater runoff. Management responses for reducing risks to water quality should consider strategies and practices robust to a range of potential future conditions.

A Dramatic Difference in Global Gene Expression between TCDD-Treated Atlantic Tomcod Larvae from the Resistant Hudson River and a Nearby Sensitive Population. Genome Biol Evol 2017.

Abstract
Atlantic tomcod in the Hudson River Estuary bioaccumulate high hepatic burdens of
environmental toxicants. Previously, we demonstrated that Hudson River tomcod developed
resistance to TCDD and PCB toxicity probably through strong natural selection during their
early life-stages for a variant of the Aryl Hydrocarbon Receptor2 (AHR2). Here, we
evaluated the genomic consequences of the resistant genotype by comparing global gene
expression in larval tomcod from the Hudson River with expression in larvae from a nearby
sensitive population (Shinnecock Bay). We developed an annotated draft tomcod genome to
explore the effects of multigenerational exposure to toxicants and a functionally impaired
AHR2 on the transcriptome. We used the tomcod genome as a reference in RNA-Seq to compare
global gene expression in tomcod larvae from the Hudson River and Shinnecock Bay after
experimental exposure of larvae to graded doses of TCDD. We found dramatic differences
between offspring from the two populations in the number of genes that were differentially
expressed at all doses (0.01, 0.1, and 1 ppb) and even in the vehicle controls. At the two
lowest TCDD doses, 250 and 1,141 genes were differentially expressed in Shinnecock Bay
larvae compared with 14 and 12, respectively, in Hudson River larvae. At the highest dose
(1.0 ppb), 934 genes were differentially expressed in Shinnecock Bay larvae and 173 in
Hudson River larvae, but only 28 (16%) of affected genes were shared among both
populations. Given the large difference between the two populations in the number and
identity of differentially expressed genes, it is likely that the AHR2 pathway interacts
directly or indirectly with many genes beyond those known in the AHR2 battery and that
other regulatory systems may also respond to TCDD exposure. The effects of chronic
multi-generational exposure to environmental toxicants on the genome of Hudson River
tomcod are much greater than previously expected.

Abstract
Over the past 50 years, mean annual water temperature in northeastern U.S. estuaries has increased by approximately 1.2°C, with most of the warming recorded in the winter and early spring. A recent survey and synthesis of data from four locations in Southern Rhode Island has led us to hypothesize that this warming may be amplified in the shallow (<1 m), nearshore portions of these estuaries. While intertidal areas are not typically selected as locations for long-term monitoring, we compiled data from published literature, theses, and reports that suggest that enhanced warming may be occurring, perhaps at rates three times higher than deeper estuarine waters. Warmer spring waters may be one of the factors influencing biota residing in intertidal regions both in general as well as at our specific sites. We observed greater abundance of fish, and size of Menidia sp., in recent (2010–2012) seine surveys compared to similar collections in 1962. While any linkages are speculative and data are preliminary, taken together they suggest that shallow intertidal portions of estuaries may be important places to look for the effects of climate change.
