The lack of high resolution, geographically diverse proxy records from the marine realm limits our understanding climate dynamics in North Atlantic Ocean and Arctic during recent centuries. We investigate impact large-scale variability on bivalve, Arctica islandica, (Linnaeus 1767) northern Norway (71°N). evaluate use annual shell growth geochemical as proxies for over centennial scales by developing a continuous, 113-yr master chronology an oxygen isotope record (δ18O) live caught material....
Horizon scanning is an increasingly common strategy to identify key research needs and frame future agendas in science. Here, we present the results of first such exercise for field sclerochronology, thereby providing overview persistent emergent questions that should be addressed by studies. Through online correspondence following 5th International Sclerochronology Conference 2019, participants submitted rated either knowledge gaps or promising applications sclerochronology. An initial list...
Abstract Long‐lived Atlantic coral species like Orbicella faveolata are important archives of oceanographic change in shallow, marine environments the Florida Keys. Not only can coral‐based records extend for multiple centuries beyond limits instrumental record, but they also provide a more accurate representation situ conditions than gridded interpolated sea‐surface temperature (SST) products nearshore reef environments. We use Sr/Ca paleothermometer to produce 150‐year (1830–1980 C.E.)...
Abstract Large‐scale, climate‐induced synchrony in the productivity of fish populations is becoming more pronounced world's oceans. As increases, a population's “portfolio” responses can be diminished, turn reducing its resilience to strong perturbation. Here we argue that costs and benefits trait synchronization, such as expression growth rate, are context dependent. Contrary prevailing views, among individuals could actually beneficial for if increases during favorable conditions, then...
Abstract In the North Atlantic Ocean, multidecadal variability in sea surface temperatures (SSTs) over past several centuries has largely been inferred through terrestrial proxies and decadally resolved marine proxies. Annually proxy records from archives provide valuable insight into this variability, but are especially rare high latitude environments, particularly for centennial timescales. We constructed continuous, absolutely dated of shell growth (1449–2014 CE; 564 years) oxygen isotope...
Abstract Our understanding of North Atlantic Ocean variability within the coupled climate system is limited by brevity instrumental records and a deficiency absolutely dated marine proxies. Here we demonstrate that spatial network stable oxygen isotope series derived from molluscan sclerochronologies (δ 18 O shell ) can provide skillful annually resolved reconstructions key components with absolute dating precision. Analyses common δ variability, using principal component analysis, highlight...
Abstract This article is composed of three independent commentaries about the state Integrated, Coordinated, Open, Networked (ICON) principles (Goldman et al., 2021, https://doi.org/10.1002/essoar.10508554.1 ) in AGU section paleoclimatology and paleoceanography (P&P), a discussion on opportunities challenges adopting them. Each commentary focuses different topic: (Section 2) Global collaboration, technology transfer application, reproducibility, data sharing infrastructure; 3) Local...
Iceland's exposure to major ocean current pathways of the central North Atlantic makes it a useful location for developing long-term proxy records past marine climate. Such provide more detailed understanding full range variability which is necessary improve predictions future changes. We constructed 225-year (1791–2015 CE) master shell growth chronology from 29 shells Arctica islandica collected at 100 m water depth in southwest Iceland (Faxaflói). The provides robust age model oxygen...
A collection of 37 near-annually-resolved proxy records is used to evaluate the main modes marine variability in North Atlantic for past 600 years. The temporal gaps data are first filled using a nesting procedure, and 19 longest time series derive linked instrumental sea surface temperature (SST) data. By comparing with other indices reconstructions, four appear most closely related 1) subtropical/subpolar SST dipole (often as an indicator Meridional Overturning Circulation [AMOC]...
Many aquatic scientists devote a significant amount of energy toward making research available and practical to policy- decision-makers as well the public at large. A recent session 2018 Ocean Sciences Meeting in Portland, Oregon brought researchers together share experiences, successes, challenges engaging audiences influencing stake-holders. Chaired by Dr. Adrienne Sponberg (Association for Limnology Oceanography) co-chaired Lisa Levin (Scripps Institution Oceanography), Mike Allen...
When was the last time you found yourself in a negotiation with mentor, peer, or current potential employer? Were successful? What were major challenges? A recent workshop at February 2018 Ocean Sciences Meeting (OSM) critically examined these types of situations goal equipping undergraduate, graduate, and early career women science strategies needed for effective, persuasive communication. The organized by COACh Program Manager Priscilla Lewis led Nancy Houfek Dr. Lee Warren. brought her...
