“…This assumption has been tested and confirmed in all reported bomb radiocarbon otolith ageing studies on marine fishes living in the surface mixed layer, whether in the south Pacific (Kalish 1993(Kalish , 1995a or the north Atlantic (Campana 1997). However, lack of synchrony has been reported in both estuarine (Carnpana & Jones 1998) and deep-sea (Kalish et al 1997) fishes. In the case of the estuarine fish, the At4C chronology reconstructed from otolith cores was phase shifted 2 to 4 yr towards earlier years, consistent with an atmospheric rather than a marine input.…”

“…The opposite is true of deep-sea waters, which were much slower to mix with surface waters containing the homb 1114C signal, and thus were characteiized by a delayed 3I4C chronology. As a result, interpretation of the A"C signal in the otolith core of a deep-sea fish can he problen~atic, and must be carefully interpreted according to depth unless the fish's juvenile phase (corresponding to the otolith core) was spent in near-surface waters (Kalish 1995b, Kalish et al 1997.…”

ABSTRACT:The fish otolith (earstone) has long been known as a timekeeper, but interest in its use as a metabolically inert environmental recorder has accelerated in recent years. In part due to technological advances, applications such as stock identification, determination of rnigralon pathways, reconstruction of temperature and salinity history, age validation, detection of anadromy, use as a natural tag and chemical mass marking have been developed, some of which are difficult or impossible to implement using alternative techniques. Microsamphg and the latest advances in beam-based probes allow many elemental assays to be coupled with daily or annual growth increments, thus providing a detailed chronologcal record of the environment. However, few workers have critically assessed the assumptions upon which the environmental reconstructions are based, or considered the possibility that elemental incorporation into the otolith may proceed differently than that into other calcified structures. This paper reviews current applications and their assumptions and suggests future directions. Particular attention is given to the premises that the elemental and isotopic composition of the otolith reflects that of the environment, and the effect of physiological filters on the resulting composition. The roles of temperature, elemental uptake into the fish and the process of otolith crystahzation are also assessed. Drawing upon recent advances i n geochemistry and paleoclirnate research as points of contrast, it appears that not all applications of otolith chemistry are firmly based, although others are destined to become powerful and perhaps routine tools for the mainstream fish biologst.

“…Analysis of bomb-produced 14 C provided successful age validation for GOM red snapper, Lutjanus campechanus, (Baker and Wilson 2001) and other commercially important species around the world (Campana 1997;Kalish et al 1997;Kerr et al 2005;Piner et al 2005). Our objective was to compare the amount of 14 C found in the cores of yellowedge grouper otoliths to previously determined 14 C levels from otoliths of red snapper and from corals to confirm the presumed birth dates determined from conventional otolith ageing.…”

Validation of yellowedge grouper, Epinephelus flavolimbatus, age using nuclear bomb-produced radiocarbon

Age validation and estimates of longevity of yellowedge grouper (Epinephelus flavolimbatus) from the Gulf of Mexico (GOM) are needed to inform fishery management decisions. Yellowedge grouper sagittal otoliths (n=100) were collected, aged using conventional means, and cores were submitted for radiocarbon ( 14 C) measurement. Radiocarbon values of yellowedge grouper otoliths were compared to established radiocarbon chronologies in the region to validate the age and ageing methodology of this species. The yellowedge grouper chronology displayed a similar sigmoidal trend as previously published chronologies. In addition to the core analysis, multiple areas on otolith sections from eight specimens were analyzed for Δ 14 C to validate age estimates for fish born prior to the 14 C increase. Our results indicate that yellowedge grouper live longer than previously reported (minimum of 40 years based on radiocarbon measurements). The validated ageing methodology supported an estimated maximum longevity of 85 years and established that yellowedge grouper have the longest lifespan currently known for any species of grouper in the GOM. Results also indicate a depth-age interaction in that material extracted from adult otolith sections assigned to post-bomb dates exhibited lower Δ 14 C values than cores (juvenile material) assigned to the same postbomb dates. This finding is likely explained by lower 14 C levels reported from water masses at deeper depths (>100 m) which are inhabited by adults.

“…The longest of the otolith records was derived from a collection of snapper Pagrus auratus from coastal waters of the North Island of New Zealand (39°S, 179°E; Kalish 1993). The closest record to ours in terms of geographic distance was derived from blue grenadier Macruronus novaezelandiae from the west coast of Tasmania (Kalish et al 1997). Based on the assumption that the growth zones in the otoliths of both species form annually, Δ 14 C data were reported with an age correction for the time since formation (Kalish 1993, Kalish et al 1997.…”

Bamboo corals (Family Isididae) are an important component of seamount benthos south of Tasmania. Besides having lifespans of up to 400 yr, little is known about their basic ecology, nor how to decode potential climate signals encoded in their skeletons. We explored the stable nitrogen isotope and radiocarbon compositions of the skeletal organic fraction of the genera Isidella, Keratoisis and Lepidisis collected from 3 Tasmanian seamounts. Analyses were performed on tissues and organic node growth rings sampled at a temporal resolution of 1 to 4 yr. Radiocarbon chronologies exhibited nuclear bomb signals characteristic of surface waters and constrained radial growth rates to ~35 ± 10 µm yr -1 for 3 specimens of the genus Lepidisis and 113 ± 17 µm yr -1 for 1 specimen of Isidella. δ 15 N values of the living tissue and underlying gorgonin were similar and averaged 9 to 12 ‰. Records of δ 15 N from 8 different specimens showed subtle, quasi-decadal patterns over the last 100 yr, although the amplitude of these features (~1 ‰) was similar to the average intra-and intercolony reproducibility. These results demonstrate the utility of deep-sea corals to track seamount biogeochemical processes over long time scales, and suggest that the extent of nutrient depletion of surface waters and associated trophic dynamics have remained relatively constant in this region over centuries. This provides an important baseline for the evaluation of the impacts of anthropogenic climate change.
