This study was conducted during the Summer of 2001, by Governor's Academy high school science class students with their teacher Susan Oleszko-Zsuts to look at the distriibution of mussels and snails in a variety of tidal creeks off the Rowley River, Rowley and Ipswich Massachusetts.
Creeks were typically sampled at a confluence and then up the corresponding two branches, labeled by distance from the confluence and yellow (Y) or blue (B) corresponding to the flagging tape used on site markers; for example, a site 100 m upstream from the confluence on Clubhead Creek would be designated Clubhead B100 or Y100. Distance up the creek was determined by stakes laid out in 50 meter intervals. Sampling was conducted at or near low tide as much as possible. At each site, the sampling transect would start at the edge of the Spartina patens zone, and continue down the creek bank until reaching the center of a drained creek or until reaching water. Quadrats were laid out by deploying a ladder-like template: 1 meter wide by 2 meter long, divided into sections at 25cm increments. This ladder would be repeatedly laid across the creek bank to cover the entire transect from S. patens to the creek center. Each section of the ladder would enclose an area of 0.25 m2 in which all mussels (Geukensia sp) and snails, Ilyanassa sp. and Littorina littoria. Notes on zonations (eg. Beginning and end of S. alterniflora zone), and surface features, as well as presence of other large organisms (eg. Oysters or other snails) were noted. NOTES AND COMMENTS: Sampling site locations were either: At the confluence of two tidal creek branches. Y or B followed by a number referring to meters upstream from the Confluence for those creeks with paired branches. A number, referring to meters upstream of an area in a creek without paired branches which is equivalent to the confluence of branched creeks. D100, referring to 100 meters downstream of the confluence or equivalent Zone: refers to the increment along the sampling ladder where organisms were counted.

Utafiti huu ulifanywa wakati wa majira ya joto ya 2001, na wanafunzi wa darasa la sayansi la shule ya sekondari ya Chuo cha Gavana na mwalimu wao Susan Oleszko-Zsuz, kuangalia usambazaji wa shellfish na konokono katika vijito mbalimbali vya mawimbi ya maji kutoka Mto Rowley, Rowley na Ipswich, Massachusetts. Kwa kawaida, mto ulichukuliwa kwenye confluence na kisha juu ya matawi mawili yanayolingana, na kutajwa kwa umbali kutoka confluence na manjano (Y) au bluu (B) inayolingana na mkanda wa alama iliyotumiwa kwenye alama za tovuti; kwa mfano, tovuti 100 m juu ya mto kutoka confluence kwenye Clubhead Creek ingepewa Clubhead B100 au Y100. Urefu wa mto huo ulipimwa kwa kutumia nguzo zilizowekwa kwa vipindi vya mita 50. Uchunguzi ulifanywa wakati wa mawimbi ya chini au karibu na mawimbi ya chini kadiri iwezekanavyo. Katika kila eneo, sampuli transect itaanza kwenye ukingo wa eneo la Spartina Patens, na kuendelea chini ya benki ya kijito hadi kufikia kituo cha kijito cha maji au hadi kufikia maji. Kwa mfano, kwa mfano, meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza za meza. Ngazi hiyo ingewekwa mara kwa mara kwenye ukingo wa kijito ili kufunika sehemu yote kutoka S. patens hadi katikati ya kijito. Kila sehemu ya ngazi hiyo ingekuwa na eneo la mraba wa mita 0.25 ambapo samaki wote (Geukensia sp.) na konokono (Ilyanassa sp.) Littorina littoria Maelezo juu ya zonations (kwa mfano. Mwanzo na mwisho wa S. alterniflora eneo), na vipengele uso, kama vile uwepo wa viumbe wengine kubwa (kwa mfano. Oysters au konokono wengine) walikuwa alibainisha. Maelezo: Sehemu ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli ya sampuli. Y au B ikifuatiwa na idadi inayoonyesha mita juu ya mto kutoka Confluence kwa wale creeks na matawi paired. Nambari, akimaanisha mita upstream ya eneo katika kijito bila matawi paired ambayo ni sawa na confluence ya vijito matawi. D100: 100m chini ya mto wa confluence au eneo sawa: inahusu ongezeko kando ya ngazi ya sampuli ambapo viumbe vimehesabiwa.
