This study simulated a 9-months warming scenario on the common seagrass Zostera marina from winter into summer (December 2015 - August 2016) in the Western Baltic Sea (Kiel Fijord), using outdoor mesocosms. Two treatments were applied: Ambient temperature regime (Ambient) and Ambient + 3.6C (Heat) over the entire course of the experiment. Temperature regimes were compared to the 22-year temperature average in the area. This dataset shows final above and below ground biomass per shoot for each shoot measured. The organization of the data is hierarchical: Treatment (Heat, Ambient), Benthocosms number (6 benthocosms per treatment), Seagrass box number (4 boxes per benthocosm), shoot number (originally 6 shoots per box, some were lost throughout the experiment). Unit of biomass is g dry weight per shoot.

Two treatments were applied: Ambient temperature regime (Ambient) and Ambient + 3.6C (Heat) over the entire course of the experiment. Temperature regimes were compared to the 22-year temperature average in the area. This dataset shows monthly or bi-monthly measurements taken of each shoot: Number of shoots [no. per box], Number of new shoots at counting event [no. per box], number of new shoots per month [no. per box per month], and number of flowering shoots [no. per box]. Derived data in %: Number of shoots [% of original shoots], number of new shoots [% of original shoots], number of flowering shoots [% of original shoots]. The organization of the data is hierarchical: Treatment (Heat, Ambient), Benthocosms number (6 benthocosms per treatment), Seagrass box number (4 boxes per benthocosm), shoot number (originally 6 shoots per box, some were lost throughout the experiment).

Two treatments were applied: Ambient temperature regime (Ambient) and Ambient + 3.6C (Heat) over the entire course of the experiment. Temperature regimes were compared to the 22-year temperature average in the area. This dataset shows daily values of salinity in each benthocosms and in the adjacent fjord. Benthocosms A1, A2, C1, C2, E1, E2 = Heat; Benthocosms B1, B2, D1, D2, F1, F2 = Ambient.

Two treatments were applied: Ambient temperature regime (Ambient) and Ambient + 3.6C (Heat) over the entire course of the experiment. Temperature regimes were compared to the 22-year temperature average in the area. This dataset shows concentrations of NO2+NO3, NH4, PO4 of each treatment (Ambient, Heat) as the mean and confidence interval (CI) across all benthocosms per treatment (n=6).

Two treatments were applied: Ambient temperature regime (Ambient) and Ambient + 3.6C (Heat) over the entire course of the experiment. Temperature regimes were compared to the 22-year temperature average in the area. This dataset shows continues temperature data for each benthocosm and the adjacent fjord. Benthocosms A1, A2, C1, C2, E1, E2 = Heat; Benthocosms B1, B2, D1, D2, F1, F2 = Ambient.
This study simulated a 9-months warming scenario on the common seagrass Zostera marina from winter into summer (December 2015 - August 2016) in the Western Baltic Sea (Kiel Fijord), using outdoor mesocosms. Two treatments were applied: Ambient temperature regime (Ambient) and Ambient + 3.6C (Heat) over the entire course of the experiment. Temperature regimes were compared to the 22-year temperature average in the area. A number of seagrass response parameters were measured throughout the experiment including parameters related to shoot mortality and reproduction (shoot abundance, growth of new shoots, abundance of flowering shoots), (ii) shoot growth (growth rate, leaf production, lengths of the 3rd leaf, number of green leaves per shoot), (ii) biomass (above and below ground biomass per shoot) and (iv) pigmentation (chlorophyll-a, beta-carotene).
