Eyeballs were collected from 31 female minke whales caught in the North Sea, Norwegian Sea and Barents Sea. The eye-lens nucleus was dissected out and the relative amount of D- and L- enantiomers of aspartic acid measured using high-performance liquid chromatography (HPLC). A racemization reaction changes the D/L aspartic acid relationship in the nucleus over time. The age of each whale was estimated using the racemization rate for fin whales along with the measured D/L ratio. The minimum age… 
Age estimation of Antarctic minke whales Balaenoptera bonaerensis based on aspartic acid racemization technique
TLDR
This study was successful in developing the AAR technique for the Antarctic minke whale, and the application of this technique can complement the age estimation of this species based on earplug readings, especially for young animals with unreadable earplugs.
Age estimation for bowhead whales (Balaena mysticetus) using aspartic acid racemisation with enhanced hydrolysis and derivatisation procedures
Accurate determination of the ages of individual whales is key to developing effective conservation strategies for the bowhead whale (Balaena mysticetus). Previous attempts to develop reliable
Update on age estimation of bowhead whales ( Balaena mysticetus ) using aspartic acid racemization
Ninety-eight eye globes (from 84 individual bowhead whales) were collected and analyzed to estimate ages of the whales using the aspartic acid racemization aging technique. Racemization rate (kAsp)
Age determination of humpback whales Megaptera novaeangliae through blubber fatty acid compositions of biopsy samples
TLDR
A potential method for ageing live free-ranging humpback whales using low-impact biopsy sampling techniques and the results suggest that it may be possible to estimate the age of individual humpbacks from any population with better than decadal resolution using this approach.
A new way to estimate the age of bowhead whales (Balaena mysticetus) using ovarian corpora counts
TLDR
Lengths and reproductive data for bowhead whales harvested by Alaskan Eskimos to estimate female reproductive parameters and age and a stone harpoon tip recovered from whale 92B2 was consistent with her corpora age of 133 years.
AGE-SPECIFIC GROWTH AND REMARKABLE LONGEVITY IN NARWHALS (MONODON MONOCEROS) FROM WEST GREENLAND AS ESTIMATED BY ASPARTIC ACID RACEMIZATION
TLDR
Eyes from 75 narwhals (Monodon monoceros) were collected in West Greenland in 1993 and 2004 for the purpose of age estimation, and age at sexual maturity was estimated to be 6–7 years for females and 9 years for males.
Online Early Version
The ages of three species of cetaceans were estimated by counting the growth layer groups (GLG) and measuring the aspartic acid racemization rate (kAsp) by what is referred to as the Aspartic Acid
Application of a novel method for age estimation of a baleen whale and a porpoise
TLDR
Correlation between chosen age estimates from AAR and GLG counts indicated that AAR might be an alternative method for estimating age in marine mammals.
Estimating the Age of West Greenland Humpback Whales Through Aspartic Acid Racemization and Eye Lens Bomb Radiocarbon Methods
To maintain a sustainable harvest of marine mammals, knowledge on key life history parameters such as age is essential. In West Greenland, humpback whale numbers were low during the 1980s due to past
Two techniques of age estimation in cetaceans: GLGs in teeth and earplugs, and measuring the AAR rate in eye lens nucleus

Age and growth estimates of bowhead whales (Balaena mysticetus) via aspartic acid racemization
TLDR
A total of 48 eye globes were collected and analyzed to estimate ages of bowhead whales using the aspartic acid racemization technique, and growth appears faster for females than males, and age at sexual maturity occurs at around 25 years of age.
Postmortem body temperatures in the minke whale, Balaenoptera acutorostrata
TLDR
Both intra- and inter-specific comparisons reveal that the thickness of the blubber layer is important for the maintenance of thermal gradients and, thereby, for heat conservation.
Use of Bone Layers to Determine Age in Minke Whales
TLDR
The number of layers in acidetched polish sections was systematically underestimated as compared with those in haematoxylin-stained sections of the same bone segment, and in stained sections the layers are distinct.
