EP19-0003. Pieces of pale fluffy substance on top of sediment in cores donated from Eulogio Soto and Eduardo Quiroga. Spicules visible under stereomicroscope. E. Quiroga compared these sponge pieces to those observed as fragments of a larger sponge in the Weddell Sea. Several small pieces pooled. Ethanol material: pieces (2 ml). Photos: Leica S8Apo, no 0.63x lens, x1.0 (all pieces): 8933, x 4.0: 8934, x8.0: 8935, x6.3: 8936...37, x4.0: 8938, x2.0: 8939, x4.0: 8940, x5.0: 8941...44. Representative photo: IMG_8933_small.JPG.

Cruise MR18-06 Leg 3. Cores 2 and 6 pooled. Core 2: 20.0 cm; base did not seal completely due to manganese nodules blocking the stopper; water was lost on deck and some sediment drained; entire contents were collected. Core 6: 28.0 cm; top of sediment was uneven and a manganese nodule was buried in the core, so collected the top 10 cm instead of 5 cm. Sediment resuspended in cold seawater, sieved over 250 um mesh, and live-sorted. Cores remained cold during all steps of processing: 20 min from recovery on deck to storage of sediment sections at 4C. Light-brown/reddish fine mud with foraminifera tests. Data from official multicore report.
