Information about geographic location of data collection: 
Data was collected and processed at two sites: Newcastle University Dove Laboratory (Cullercoats, UK) and AkzoNobel (Gateshead, UK)
1) Hartlepool Marina
	Marine Biofilms grown in-field under low flow (~ 2000 L/H) and high flow (~ 4000 L/H) in two marine biofouling flow cells.
	
2) AkzoNobel
	Preparing and painting panels for fouling. 
	Optical Coherence Tomography (OCT) - structural data of marine biofilms
	Flow cell with incorporated pressure drop system for calculating biofilm-associated drag 
	Digital microscope for qualitative analysis

DATA & FILE OVERVIEW 
--------------------

This dataset contains:

Each file refers to sructural and mechanical data collected for three different types of coloured coupon (4cm dia.): red, white and black.
	
Each excel file has a README tab incorporated but briefly: 
1) HartlepoolBiofilms_DragData.xlsx - Data from flow cell runs testing the drag associated with biofilms grown in Hartlepool Marina. The worksheets within the
	workbook show the calculation of Fanning Friction Factor (Cf) for each fouled panel and smooth PVC panels. Worksheets are split by replicate number and 
	flow condition (low or high flow) during growth and there is an averages spreadsheet for each condition too. Wihtin each worksheet there is a Cf vs Re
	curve (the drag curve) and pressure drop vs u^2 which indicated whether flow is tubrulent. There is a summary of the averages data in the 'Plots' worksheet:
	a Cf vs Re curve for lowflow, highflow and smooth PVC, as well as Cf vs Re curves for individual replicates.  

2) HartlepoolBiofilms_SingleFrictionFactor.xlsx - This workbook is linked to the DragData workbook (above) by taking the slope of the line from pressure drop vs.
	u^2 plots a single instantaneous Cf can be calculated. The equation for this is given in the workbook. Results of statistical tests are also given and 
	show that average shear modulus sig. effected average instantaneous Cf. 

3) HartlepoolBiofilms_ShearModulus.xlsx - The shear modulus data calculated from OCT 2D-scans by manually measuring angles of deformation using Fiji, ImageJ. 
	The worksheets within are split by replicate number and flow condition (low or high flow) during growth and there is an averages spreadsheet for each
	condition too. The 'Summary' worksheet shows stress-strain plots. 

4) HartlepoolBiofilms_OCTStructuralData.xlsx - Data from processing OCT 3D-scans in MATLAB to provide measurements of biofilm structre: thicknes, roughness, biomass, 
	percent cover and volume. Worksheets are split by replicate number and flow condition (low or high flow) during growth and there is an averages spreadsheet 
	for each condition. Plots have been provided within the workbook to show how structure changed under increasing flow velcoity druing the flow cell cycle.
