“…The relationship between temperature and δ 18 O variation in fish otoliths is well established in the ecological literature, and more specifically for Pacific cod and yellowfin sole in the Bering Sea and Gulf of Alaska . Applying this understanding to the current study of patterns of δ 18 O variation in Pacific cod otoliths suggests evidence of thermal habitat change over the life of 5‐ to 6‐year‐old Pacific cod, as well as seasonal variation in the temperature experienced by fish.…”

“…The well‐established relationship between temperature and δ 18 O values has been used in a variety of studies. High‐resolution δ 18 O measurements of marine coral and shells and fish otoliths have proven useful to derive environmental temperature and salinity profiles over the lifetime of an organism . Grossman and Ku documented the relationship between temperature and δ 18 O values in aragonite foraminifera.…”

Both techniques resolved δ O life-history signatures and showed patterns consistent with seasonal variation in temperatures and changes due to fish migration. When otoliths are large, micromilling/IRMS can provide adequate resolution for fish age validation. However, SIMS is the better option if greater sampling resolution is required, such as when otoliths are small or specimens are longer lived and have compact growth zones.

“…Individual serially sampled ammonites may have any trajectory within this modeled range. Recent serially sampled ammonites that lived in similar water column conditions show divergent patterns of δ 18 O (Landman et al, 2018b;Linzmeier et al, 2018) and recent otoliths show similar patterns (Helser et al, 2017 (Sessa et al, 2015). The skew of the distributions reported (+0.3 and +0.4) was not reproduced from temperature alone, but could potentially be due to freshwater influence coupled to temperature seasonality (Sessa et al, 2015).…”

Serially sampled δ18O 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 δ18O 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 δ18O profile in a free-swimming organism: swimming behavior, seasonal water column temperature change, and time averaging in sampling. Model results indicate that seasonal variability in δ18O 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 δ18O 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 δ18O (~4‰) are possible within and between individuals in settings with persistent thermoclines like the tropics, depending on the swimming depth limits and behavior of individuals. These results suggest that future interpretation of serially sampled δ18O should consider seasonal water column variation from either modern or modeling sources in addition to comparison to co-occurring benthic and planktic organisms. Additionally, this modeling casts doubt on the promise of isotope sclerochronology alone as a growth chronometer in ammonites and other free-swimming fossil organisms and highlights the need for other methods of quantitatively determining age.

“…Recent developments in secondary ion mass spectrometry (SIMS) δ 18 O analysis of otoliths have enabled a high-resolution reconstruction of migration and life history characteristics of marine species (Hanson et al 2010, Matta et al 2013, Shiao et al 2014, Helser et al 2018a, Shirai et al 2018, Willmes et al 2019. Unlike conventional IRMS, SIMS is capable of determining isotopic composition within a spatial resolution of 5 to 15 μm, which allows subannual, seasonal, and even weekly or much shorter timescale analyses with high accuracy and precision (Kita et al 2009, Valley & Kita 2009.…”

This study aimed to reconstruct temperatures experienced during the larval period by adult Pacific bluefin tuna Thunnus orientalis using high-resolution otolith stable oxygen isotope (δ18O) analysis. A novel otolith sample preparation protocol for secondary ion mass spectrometry (SIMS) analysis developed in this study reduced the background noise of SIMS measurements, enabling analyses of >10 times higher resolution around the otolith core compared to previous studies using conventional isotope ratio mass spectrometry (IRMS). The values obtained from SIMS were compared to those obtained by microvolume δ18Ootolith analysis using micromilling and conventional continuous-flow IRMS (CF-IRMS). There was a systematic offset (average 0.41‰ with SIMS resulting in lower values) most likely caused by matrix effects on SIMS δ18Ootolith values that can be calibrated using a strong linear relationship between SIMS and CF-IRMS measurements (r2 = 0.78, p < 0.001). The core-to-edge δ18Ootolith of 5 Pacific bluefin tuna revealed fine-scale seasonal variations in water temperature agreeing with known migration patterns. In addition, the ambient water temperature experienced during larval stages (about 10-20 d post hatch) estimated from otolith core δ18O ranged from 26.7 to 30.7°C, overlapping with temperatures associated with the occurrence of larval Pacific bluefin tuna. Combining SIMS and microvolume CF-IRMS δ18O otolith analyses offers a microscale examination of fish ecology that is not possible with conventional IRMS techniques. This novel method is particularly useful for understanding the early life history of fish that may be affected by climate change and reconstructing a well-resolved migration history for fish species that have small otoliths and/or narrow growth increments.
