Harp Seals in the Icelandic Archaeofauna: Sea Ice and Hard Times of harp seals in nets (Kristjánsson 1980, 361-62). Hunting methods were therefore applied according to sea ice conditions i.e. uppidráp on ice when appropriate and nets when sea ice was limited or absent. This was not an activity restricted to hard times and nor was it opportunistic; as borne out by the legal allocation, auctioning and leas- ing of sealing rights and the apparent mar- ket in harp seal derivatives i.e. the price on derivatives implies a commodity. Twentieth century surveys of harp seals in Icelandic waters (Hauksson 1986; Hauksson & Bogason 1997; Folkow et al. 2004) demonstrate that: • Harp seals frorn Jan Mayen spend a great deal of time migrating through open water between the various quar- ters of the Greenland Sea and beyond; including Icelandic inshore waters. • Harp seals are oífen found in Icelandic waters when sea ice is absent. • Harp seals found in Icelandic waters are predominantly less than one year old. • Harp seals are usually found in Icelandic waters during winter and spring. • Harp seals enter into Icelandic waters in search of prey i.e. capelin. The first two points challenge the assump- tion that harp seal bone found in the archaeological record was accumulated ex- clusively during periods of extreme or se- vere sea ice in Icelandic waters. Nor should reference to harp seal pups in historical ac- counts or the presence of neonate harp seal bone in archaeofaunas necessarily suggest that there were harp seal whelping areas (and therefore sea ice) near Iceland. While the interpretation of the Svalbarð neonatal assemblage remains viable, with neonate harp seals less than one month old, it is worth noting that young harp seals, once weaned, can potentially disperse into Ice- landic coastal waters once they abandon the sea ice in the whelping area (as early as 6 weeks old) (Ronald & Healey 1981; Amorosi 1992). This has some bearing on the interpretation of the Akurvík assem- blage and the assessment of new material from Svalbarð and other Icelandic archaeo- faunas (Amorosi 1996, 168). The parity between the archaeological, historical and ecological data with regard to the distribution of harp seals in Iceland and its surrounding waters is striking and includes areas that are not commonly in- undated by sea ice (Vilmundarson 1969, 313-32), in particular Icelands south coast (Fig. 3). It is however important to ac- knowledge the absence of harp seal bone in seal bone assemblages from Breiðafjörður i.e. Miðbær (Flatey) and Innri Hvanney (Bjarneyjar), despite the historical and modern evidence for their, albeit limited, presence there (Amorosi 1996, 982-88; Woollett 2007). With regard to seasonality, there is a re- markable consistency in the timing of harp 67
