Fig. 4: Along-canyon overview of the observations showing the spread of dye along the canyon.
From: Observations of diapycnal upwelling within a sloping submarine canyon
The inset axes show time-mean profiles of along-canyon velocity at MP1 (located at 11.3 km along the canyon, averaged over the full 1-week record) and MP2 (located at 4.8 km along the canyon, averaged over the full 3-month record; MP2 was deployed after MP1 was taken out of the water). Dye concentration from an example transect 20 hours after the dye release along the canyon axis is shown between 5.5 km and 8 km, with the highest concentrations shown with dark pink colours (see Extended Data Fig. 5d for more detail). The 3.85 °C isotherm is contoured in black. The coloured dots show the dye concentration measured using the fluorometer on the MP1 mooring also at 20 hours after release. Colour scales for the dye transect and moored profile dye concentrations are different and the detection threshold is 0.06 ppb for the FCTD measurements and 0.006 ppb for the MP1 measurement. Depths of the 3.85 °C and 3.53 °C isotherms 20 hours after release are marked with black crosses on the MP1 profile.
