'Biogenic silica' are biogenic silicon minerals which originate from the siliceous skeletal material of dead diatoms and other silica-utilizing organisms. Daniel On 18.05.2018 09:47, Lowry,

Re: [CF-metadata] No standard names for element concentrations in sediment?

Dear Daniel, I think benthos chemistry is virgin territory for CF - not really surprising for a standard that started in the atmosphere before dipping its toes in the ocean. Some thoughts based on my experience with observed sediment chemistry data. The data may be reported per unit mass

Re: [CF-metadata] proposed new standard name for storm surge residual

Dear Andy, I agree with Jonathan that specifically referencing LAT in the Standard Name would be better. In the UK sea level community there is a tendency to use the term 'chart datum' when what is really meant is 'Admiralty Chart Datum', which is defined as LAT. Some other navies (e.g.
