This Theme Section on the innovative use of sclerochronology was motivated by the cross-disciplinary session ‘Looking backwards to move ahead — how the wider application of new technologies to interpret scale, otolith, statolith and other biomineralised age-registering structures could improve management of natural resources’ convened at the 2016 ICES Annual Science Conference in Riga, Latvia. The contributions to this Theme Section provide examples of applications to improve the assessment and management of populations and habitats, or showcase the potential for sclerochronology to provide a deeper understanding of the inter - action between marine life and its environment, including the effects of changing climate.

  • Geoscience Department of Geography & Geology Program Review 2007-2014
    University of North Carolina Wilmington Master of Science in Geoscience Department of Geography & Geology Program Review 2007-2014 Self-Study December 2014 Self-Study Program Review Committee: Joanne Halls, Chair Michael Smith, Geoscience Graduate Coordinator Andrea Hawkes, Todd LaMaskin, Scott Nooner Executive Summary The UNC Wilmington Department of Geography and Geology began in 1970 and has grown to be a thriving and vital component of the Earth sciences at both undergraduate and graduate levels. The department currently has 19 tenure-track faculty, 2 lecturers, 1.5 staff people who support four undergraduate (geography, geoscience, geology, and oceanography) and two graduate (geoscience and geospatial technology) programs. Within the past 5 years the department has had several changes in faculty composition through retirements/departures and new hires. The degree programs have also changed substantially where the MS in Geology has become the MS in Geoscience. The result is a growth in our graduate program from 24 students in 2013 to 43 students in 2014. The greatest challenge that has consistently affected the Department is space. The faculty are spread across campuses (Center for Marine Science and main campus) and buildings, there is insufficient research space for faculty and students on the main campus, and the space is in need of refurbishment to accommodate the latest trends in science and technology. The greatest challenge for the MS in Geoscience program are the student stipends. The number of stipends and the funding amount is far less than comparable programs within North Carolina and in the mid-Atlantic region. It is a strong testament to the recruiting efforts of Department faculty that given this low funding the program has grown so quickly over the past few years.

  • Refining the Interpretation of Oxygen Isotope Variability in Free-Swimming Organisms

Linzmeier1 Received: 31 August 2018 / Accepted: 14 February 2019 / Published online: 28 March 2019 Ó Akademie der Naturwissenschaften Schweiz (SCNAT) 2019 Abstract Serially sampled oxygen isotope ratios (d18O) from fossil and modern cephalopods may provide new insight into the behavior and longevity of individuals. Interpretation of these data is generally more difficult than similar data from bivalves or brachiopods because the measured d18O from shell combines both seasonal change and depth change over the life of an individual. In this paper, a simple null model is presented combining the three fundamental controls on a measured d18O profile in a free-swimming organism: swimming behavior, seasonal water column change, and time averaging in sampling. Model results indicate that seasonal variability in d18O in a free-swimming organism can be interpreted in locations with strong seasonality through most of the swimming range but is complicated by swimming velocity and is sometimes best expressed by changes in d18O variance rather than simple sinusoidal patterns. In other locations with a stable thermocline or seasonal ranges in only a small portion of the water column, no variability caused by seasonality would be expected. Furthermore, large ranges of d18O(* 4%) are possible within and between individuals in settings with persistent ther- moclines like the tropics, depending on the swimming depth limits and behavior of individuals. These results suggest that future interpretation of serially sampled d18O should consider seasonal water column variation from either modern or modeling sources in addition to comparison to co-occurring benthic and planktonic organisms.

  • Fossil Bivalves and the Sclerochronological Reawakening
    Paleobiology, 2021, pp. 1–23 DOI: 10.1017/pab.2021.16 Review Fossil bivalves and the sclerochronological reawakening David K. Moss* , Linda C. Ivany, and Douglas S. Jones Abstract.—The field of sclerochronology has long been known to paleobiologists. Yet, despite the central role of growth rate, age, and body size in questions related to macroevolution and evolutionary ecology, these types of studies and the data they produce have received only episodic attention from paleobiologists since the field’s inception in the 1960s. It is time to reconsider their potential. Not only can sclerochrono- logical data help to address long-standing questions in paleobiology, but they can also bring to light new questions that would otherwise have been impossible to address. For example, growth rate and life-span data, the very data afforded by chronological growth increments, are essential to answer questions related not only to heterochrony and hence evolutionary mechanisms, but also to body size and organism ener- getics across the Phanerozoic. While numerous fossil organisms have accretionary skeletons, bivalves offer perhaps one of the most tangible and intriguing pathways forward, because they exhibit clear, typically annual, growth increments and they include some of the longest-lived, non-colonial animals on the planet. In addition to their longevity, modern bivalves also show a latitudinal gradient of increasing life span and decreasing growth rate with latitude that might be related to the latitudinal diversity gradient. Is this a recently developed phenomenon or has it characterized much of the group’s history? When and how did extreme longevity evolve in the Bivalvia? What insights can the growth increments of fossil bivalves provide about hypotheses for energetics through time? In spite of the relative ease with which the tools of sclerochronology can be applied to these questions, paleobiologists have been slow to adopt sclerochrono- logical approaches.

The Southern Ocean ecosystem remains largely unstudied in part for its remote- ness, extreme climate and strong seasonality. This lack of knowledge, some of it even on basic biological information, it is especially worrying due to ongoing climate-driven changes that the Southern Ocean ecosystem is experiencing. Lack of long-term in situ instrumental series has also being a detriment to understand long-term feedbacks between the physical environment and the ecosystem. Sclerochronology, the study of periodic accretional patterns in the hard body structures of living organisms, has contributed to a wide range of Antarctic research disciplines (e.g.

Scipione Ponte 1, Salsomaggiore Terme, 43039, Italy Keywords: Sclerochemistry; stable isotope; Mediterranean Sea; fossil archive ABSTRACT ACCEPTED MANUSCRIPT Understanding the transformations of the climate system may help to predict and reduce the effects of global climate change. The geological record provides a unique archive that documents the long-term fluctuations of environmental variables, such as seasonal change. Here, we investigate how seasonal variation in seawater temperatures varied in the Mediterranean Sea during the early Pleistocene, approaching the Early-Middle Pleistocene Transition (EMPT) and the beginning of precession-driven Quaternary-style glacial-interglacial cycles. We performed whole-shell and sclerochemical stable isotope analyses (δ18 O, δ13 C) on bivalves, collected from ACCEPTED MANUSCRIPT the lower Pleistocene Arda River marine succession (northern Italy), after checking shell preservation.
