Instructions for data submission to TIDE Project Database

http://ecosystems.mbl.edu/tide

***Read the following guidelines carefully and double-check your data files to ensure they are in the proper format for submission to the TIDE database***

Guidelines for data submission:

· All project participants are required to submit their data to the TIDE database in a timely matter

· All submitted data files will be posted on the TIDE webpage and accessible to all project members as well as the general online community

· Submitted data must contain two parts; 1) a tab delimited (.txt) file or excel file (.xls) containing the actual data and 2) a metadata documentation file in MS word (.doc) describing the dataset (see templates for data file and documentation file)

· The .txt or .xls file and .doc file will be posted online under the appropriate subheading and referenced with a general TIDE data cover page describing guidelines for data use and publication (see below)

· The data file and documentation file must have the same name (different extension). The appropriate name for a data file includes the initials of the PI, abbreviated creek name, abbreviated sampling description, and year data was collected (see examples under documentation file template). The data-manager may edit names as appropriate.

· Data submissions and web posting will be managed by the MBL-based RA in charge of the database. Data submissions and any questions about the database should be sent to this individual (currently Mike Johnson)

Below is an example of the cover page that will be used to access each submitted data file. This page will be constructed by the TIDE database manager from the information included in each submitted documentation file.

Acceptance and utilization of TIDE data requires that:

· The Project Principal Investigator (Linda Deegan) should be sent a notice stating reasons for acquiring any data and a description of the publication intentions.

· The Principal Investigator of the data set be sent a copy of the report or manuscript prior to submission and be adequately cited in any resultant publications.

· A copy of any resultant publications should be sent to:

BRIEF DESCRIPTION OF DATA FILE:

Tidal creek benthic chlorophyll

KEYWORDS: tidal, creek, benthic, sweeney, club head, nelson, sand, shad, sawyer, west, mud, greenwood, chlorophyll

RESEARCH LOCATION:

Creek

Branch

Transect

Habitat

EXPERIMENTAL DESIGN AND METHODS:

Benthic sediments were collected at low tide using 60 cc syringe corers with 2.65 cm diameters. Surface to 2 cm depths were sectioned and placed in 60 cc polypropylene centrifuge tubes and frozen for later chlorophyll extraction (see ANALYTICAL METHODS).Total volume of sediment is 11.03 cc.

Habitat	Sediment habitat type, marsh or plant type
Chla areal	Areal concentration of benthic chlorophyll a	Milligrams per square meter	1
Phaeo areal	Areal concentration of phaeophytin	Milligrams per square meter	1
Chla conc	Volumetric concentration of benthic chlorophyll a	Milligrams per cubic meter	1
Phaeo conc	Volumetric concentration of benthic phaeophytin	Milligrams per cubic meter	1
%loss	% loss on ignition of sediment weight	percent	.01

Bulk Density	Bulk density of sediment	Grams per cubic centimeter of sediment	.001
Comments	Comments about specific data

Comments	Comments about specific data

CALCULATIONS:

% loss on ignition = (dry wt – ash wt)/dry wt

Porosity = (wet wt – dry wt)/wet wt

Bulk density = dry wt(g)/sediment volume (cc)

Mg/m2 = mg/m3 x depth (.02m)
