Which navigation error increased for ships using sextants in higher latitudes during the 18th century?

💡 Explanation

When using sextants at high latitudes, the apparent angle between the horizon and celestial bodies is susceptible to greater distortion from atmospheric refraction because the observer's line-of-sight passes through more atmosphere at a shallower angle. Therefore, latitudinal error increases, rather than longitude error, magnetic variation, or speed mistakes that arise from distinct sources.
