Sampling date 04/2011. Scale bars indicate 25 µm (1), 50 µm (2), 25 µm (3).Three images.First:The image shows numerous chitinous spines (typical for Thalassiosirales) which minimize their sedimentation speed.Second:The oblique view exhibits short silicous spines, the so called occluded processes. On the lower left, lower right and central above chitinous spines are visible.Third:The oblique view exhibits short silicous spines, the so called occluded processes. On the lower left near the scale bar a chitinous spine is visible.Please click on < or > on the image edges or on the dots at the bottom edge of the images to browse through the slides!Place name: North Sea around HeligolandLatitude: 54.186311     Longitude: 7.895034Microscope Zeiss Universal, camera Olympus C7070WZ.

Scale bars indicate 50 µm.Two images.First:The image shows numerous chitinous spines (typical for Thalassiosirales) which minimize their sedimentation speed.Second:The oblique view exhibits short silicous spines, the so called occluded processes. Some chitinous spines protruding from the fultoportulae (also called strutted processes) along the dotted valve margin are also visible.Please click on < or > on the image edges or on the dots at the bottom edge of the images to browse through the slides!Place name: North Sea around HeligolandLatitude: 54.186311     Longitude: 7.895034Microscope Zeiss Universal, camera Olympus C7070WZ.
