Resumen

Small, frequent calving events dominate the behavior of most Arctic marine‐terminating glaciers,yet their oceanographic impacts remain largely unquantified. We present the first direct observations of internalwaves generated by modest ice‐fall calving at Kronebreen, Svalbard. High‐resolution current meter andmicrostructure measurements show that each event excites weakly nonlinear multi‐modal internal wave packetswith ∼4 m vertical displacements and mode 1 propagation speeds of 0.35–0.42 ms
