These numbers come from web analytics and reflect real user activity on the site. They reliably show dataset usage and are mostly free of bot traffic.

Krill were collected from surface waters (upper 50 m) at each sampling station during the nighttime using a 60-cm diameter Bongo frame equipped with black 335-μm mesh nets and non-filtering cod ends towed for <10 min at 2-3 kts. Healthy female E. pacifica (obvious ovary) were identified under a microscope, kept chilled (10-14 °C) at all times, and were gently transferred using broad spoons to prevent damage.
